Exchange Server 2010 - High Availability and Disaster Recovery - English (United States)

We have 2 Exchange 2010 servers and trying to setup HA/failover using DAG setup with DNS Round Robin
Both servers have mailbox, CAS and Hub roles. We are planning to configure DAG and then setup Network Balancing through DNS Round Robin by creating multiple A records for MX record on the external DNS and internal DNS with minimum TTL. My question is what
will happen to the emails in transit if one of the servers goes down ?
I hope this makes sense
Thank you

Hi,
Based on my knowledge, the message can still be delivered.
Let's look at the process for internal mail flow here:
1. Microsoft Exchange Mail Submission service
- Notifies a Hub Transport server role in the local Active Directory site when a message is available for retrieval from a sender’s Outbox
2. Store driver
- Retrieves messages from sender’s Outbox
4. Submission queue
- Stores all messages on disk until processed
5. Categorizer
- Processes one message at a time from the Submission queue
6. Store driver or Send connecotor
- Delivers the message to user mailbox if the mailbox is withing the site or in case if it is on remote server delivers the message through a Send connector.
In your case, the server suddenly goes down after you send message, the messages will be received at last.
When it comes to DNS round robin for CAS servers, we usually consider the Outlook connectivity. If one CAS connected fails, then Outlook will try to re-establish connectivity to the other IP address.

SQL Server 2005 High Availability and Disaster Recovery options

Hi, We are are working on a High Availability & Disaster Recovery Planning solution for an application database which is on SQL Server 2005. What different options have we got to implement this for SQL Server 2005 and after we have everything setup how
do we test the failover is working?
Thanks in advance.........
Ione

DR : Disaster recovery is the best option for the business to minimize their data loss and downtime. The SQL server has a number of native options. But, everything is depends upon your recovery time objective RTO and recovery point objective RPO.
1. Data center disaster
Geo Clustering
2. Server(Host)/Drive (Except shared drive) disaster
Clustering
3. Database/Drive disaster
Database mirroring
Log shipping
Replication
Log shipping
Log shipping is the process of automating the full database backup and transaction log on a production server and then automatically restores them on to the secondary (standby) server.
Log shipping will work either Full or Bulk logged recovery model.
You can also configure log shipping in the single SQL instance.
The Stand by database can be either restoring or read only (standby).
The manual fail over is required to bring the database online.
Some data can be lost (15 minutes).
Peer-to-Peer Transactional Replication
Peer-to-peer transactional replication is designed for applications that might read or might modify the data in any database that participates in replication. Additionally, if any servers that host the databases are unavailable, you can modify the application
to route traffic to the remaining servers. The remaining servers contain same copies of the data.
Clustering
Clustering is a combination of one or more servers it will automatically allow one physical server to take over the tasks of another physical server that has failed. Its not a real disaster recovery solution because if the shared drive unavailable we cannot
bring the database to online.
Clustering is best option it provides a minimum downtime (like 5 minutes) and data loss in case any data center (Geo) or server failure.
Clustering needs extra hardware/server and it’s more expensive.
Database mirroring
Database mirroring introduced in 2005 onwards. Database Mirroring maintain an exact copy of a database on a different server. It has automatic fail over option and mainly helps to increase the database availability too.
Database mirroring only works FULL recovery model.
This needs two instances.
Mirror database always in restoring state.

HADR Considerations
Need to Understand the business motivations and regulatory requirements that are driving the customer's HA/DR requirements. Understand how your customer categorizes the workload from an HA/DR perspective. There is likely to be an alignment between the needs
and categorization.
Check for both the recovery time objective (RTO) and the recovery point objective (RPO) for different workload categories, for both a failure within a data center (local high availability) and a total data center failure (disaster recovery). While RPO and
RTO vary for different workloads because of business, cost, or technological considerations, customers may prefer a single technical solution for ease in operations. However, a single technical solution may require trade-offs that need to be discussed with
customers so that their expectations are set appropriately.
Check and understand if there is an organizational preference for a particular HA/DR technology. Customers may have a preference because of previous experiences, established operational procedures, or simply the desire for uniformity across databases from
different vendors. Understand the motives behind a preference: A customers' preference for HA/DR may not be because of the functions and features of the HA/DR technology. For example, a customer may decide to adopt a third-party solution for DR to maintain
a single operational procedure. For this reason, using HA/DR technology provided by a SAN vendor (such as EMC SRDF) is a popular approach.
To design and adopt an HA/DR solution it is also important to understand the implications of applying maintenance to both hardware and software (including Windows security patching). Database mirroring is often adopted to minimize the service disruption
to achieve this objective.
HADR Options :
Failover clustering for HA and database mirroring for DR.
Synchronous database mirroring for HA/DR and log shipping for additional DR.
Geo-cluster for HA/DR and log shipping for additional DR.
Failover clustering for HA and storage area network (SAN)-based replication for DR.
Peer-to-peer replication for HA and DR (and reporting).
Backup & Restore ( DR)
keep your server DB backups in network location ( DR)
Always keep your sql server 2005 upto date, in case if you are not getting any official support from MS then you have to take care of any critical issues and more..

How to configure high availability and disaster recovery? And user authenticate

We are in the process of rolling out our online help which was created using Robohelp. In our initial rollout we will provide access to the files via our Client Portal which requires authentication. We are also planning for our next version where we intend to implement Robohelp server functionality.
Our IT team is looking at options on how to configure for High Availability and Disaster Recovery. It seems that Robohelp doesn't have any built-in functionality in this area. In addition we require that our users authenticate. The options for the server version seem to be more internally focused and we would need to solution the authentication using a third party.
Would anyone be willing to share their approach in these areas? Would you be willing to participate in a conference call with our IT Professionals?

Hello again
I see my good friend Peter replied to your LInkedIn post where you cross-posted the same question. For those here that have no clue what Peter stated, here it is:
What are you seeking to recover? Your projects? Your outputs? This sounds like a question more appropriate to Disaster Recovery consultants and far wider reaching than RoboHelp. To me it seems like a question your IT people should be asking direct to such consultants who would expect a fee for their advice.
I would agree with Peter's reply.
I'll also go further and ask what exactly is being done in this realm for the application? Help files generally are there to support an application on the server. So whatever you are doing for the applciation should also be able to be used for the WebHelp, FlashHelp or web based AIR Help files, no?
Cheers... Rick

Move Exchange Server 2010 SP1 databases and log files to another partition

My company has been running Exchange Server 2010 SP1 on virtual machine for almost three years. My colleague created this virtual machine (Windows Server 2008 R2 SP1) before Exchange Server installation with following partitions:
C partition - for Windows Server 2008 R2 SP1 OS (size 40 GB)
E partition - for Exchange Server 2010 SP1 databases and logs (size 410 GB)
Those two partitions are on the same virtual hard disk "next to one another" so I can not extend C partition which gets filled up with IIS logs (when C partition free space is under 10 GB I am backing up these logs with backup software and afterwards
deleting them thus freeing up space on C partition). I have 2 databases (along with Public Folders) and size of these databases and their logs is around 235 GB.
Is it safe to move these databases and their logs to another partition which I would create on separate virtual hard disk for this purpose only and how much time this process might take since during this process databases
would be dismounted and inaccessible to all users? He made big blunder in my opinion but I have to solve this.

Yes, its safe to move the DB/Logs. You can follow the procedure mentioned in this article to do it via EMC or Shell... http://exchangeserverpro.com/move-exchange-2010-database-folder/
But it depends on various factors on how long it is going take, like size of the database/logs, server performance, storage performance etc...
Besides this, upgrade Exchange 2010 SP1 to SP3, SP1/SP2 aren't supported anymore! http://blogs.technet.com/b/rmilne/archive/2014/04/09/end-of-exchange-2010-sp2-support.aspx

Exchange Server 2010 - DAG - Physical and Virtual

Hi All,
we are trying to configure Exchange Server 2010 SP1 DAG with TWO Servers, we are getting the error sector size on log file header was mismatch
1) Physical Server - when we check the sector size on log file - 512 bytes   (RAID5)
2) Virtual Server - when we check the sector size on log file - 4096 bytes
is there any workaround to solve this issue or do i need to re-install the physical server with 4096 sector size..
When i check the Volume details on both machine
1)
Bytes Per Sector :               512
Bytes Per Physical Sector :       <Not Supported>
Bytes Per Cluster :               4096
Bytes Per FileRecord Segment    : 1024
2)
Bytes Per Sector :               512
Bytes Per Physical Sector : 4096
Bytes Per Cluster :               4096
Bytes Per FileRecord Segment    : 1024

Hi Jared,
I've got a question regarding your answer.
We have an existing Exchange 2010 DAG configuration with 3 mailbox servers in NL and 3 in the UK.
2 for normal databases at each site and 1 for Archive databases at each site.
The current Mailbox servers for the Archive databases are Hyper V 2008 R2 based VM's with a passthrough for storing the databases.
We now want add 1 new Mailbox server for storing archive databases at each site and add them to the DAG.
Can we use Windows 2012 Hyper-V hosts and create the new VM's with 4k sectorsize vhdx files for the new mailbox servers ?
Regards

Exchange Server 2013: Deploying High Availability and Site Resilience

Dear All,
I'm planning to Deploying High Availability and Site Resilience.
I have two data center and I have one exchange server on each site (multi-role).
I want to deploy Database Availability Group.
Is it possible? any idea?
in addition, all clients is connected to their email to their own site. dose it has any affected to Outlook users?

Hi MAS,
Currently, I have only mailbox server and only database for each site.
+ Site1: I has DB1 and all users in site1 will access to their own site. (MBX1) subnet 192.168.1.0/24
+ Site2: I has DB2 and all users in site2 will access to their own site. (MBX2) subnet 192.168.2.0/24
But the email for incoming and outgoing with external will go to Site1.
In Planning,
I want to implement DAG to provide HA on database level below:
Is it possible to do that? dose it has any affected to current Outlook users?

Exchange Server 2010 SP3 Databases are not mounting after the recovery process

Hi,
We are using Exchange server 2010 SP3 in our office. Databases are stored in an ISCSI drive mapped with the exchange. We are taking daily full backup of my Exchange server using Symantec Backup exe 2012. As a testing purpose I created a test environment
same like my existing live environment to check the disaster recovery and backup. Thankfully disaster recovery worked well and I am able to open the exchange management console and powershell. But I am not able to mount the recovered databases ending
with an error saying "Couldn't mount the database that you specified. Specified database: officialrecover; Error code:
An Active Manager operation failed.........." and even I am not able to use the utility eseutil.exe to the database with an error "access to source database failed with jet error 1811". I am able to create a new database and mount
it.
I am using Windows Server Ent 2008 R2 64 Bit with Exchange Server 2010 SP3 in the Live environment with 3 partitions called C (279 GB), E (4.46 TB, ISCSI), F (976 GB) in my Live environment.
For test it is Windows Server Ent 2008 R2 64 Bit with Exchange Server 2010 SP3 with 3 partitions C (240 GB), E (1.4 TB), & F (240 GB).
Please help me with your valid comments to solve and mount the database and close the issue for ever.
With Regards
Jay

Jared is correct that in essence the message is saying the DB cannot be found.
When you restored to your recovery server are all the paths the same, i.e. if the DB existed on E:\XYZ on the production server it must be the same on the recovery server
When you restored into the recovery site do you have AD restored into that site as well?
For the recovery server are you using iSCSI storage for it as well? If so am I correct to assume that you have copies of the databases just for use on this server and are not trying to reference the same instance of the DB from the production
and test/recovery server?
I have also seen an issue where DB's getting written to disk from Symantec mess up the header of the DB. If you want to validate that the DB is actually intact and accessible you might want to check out our DigiScope product
http://www.lucid8.com/product/digiscope.asp using a free DEMO license. If it works i.e. you are able to mount in DigiScope from same location where its failing on the recovery server we know the
DB your pointing at is good and accessible from the current path but something else is amiss in your configuration

Windows Server 2008 R2 Standard "Certificate Authority Service" / Exchange Server 2010 EMC not starting and no AD connectivity for authentication.

Hello,
I am a new IT Manager at this company and need assistance big time. Their environment looks as follows:
Server 1. Domain Controller Server (Windows Server 2008 R2 Standard) running active directory.
Server 2. Email Server (Windows Server 2008 R2 Standard) running Exchange Server 2010 .
* Note. No back ups to work with aside from whats mentioned below.
DC had a virus infection causing a lot of issues on the shared network drives 2 days ago locking up all the files with a crypto ransom virus. Running Avast suppressed the infection. Had to recover the file shares which luckily had a back up.
The issue is that the Exchange Server 2 post this lost connectivity with the AD Server 1. Exchange Server 2 when launching EMC could not launch the console stating the following:
"No Exchange servers are available in any Active Directory sites. You can’t connect to remote
Powershell on a computer that only has the Management Tools role installed."
Shortly after I found that it is possible the EMC launcher was corrupt and needed to be reinstalled following another blog post. I deleted the exchange management console.msc per instructions only to discover I couldnt relaunch it because there was
no way how. So I copied another msc file that happened to be on the DC Server 1 back to Exchange Server 2 and got it to launch again.
Another post said that it might be an issue with the Domain Account for the Computer, so to delete it in the AD Server 1 only to find that rejoining it from Exchange Server 2 using Computer>Properties> Chage Settings > Change is greyed out because
it is using the Certificate Authority Service.
I tried manually re-adding the computer in AD and modeling permissions after another server in group settings but no go. After this I was unable to login to the Exchange Server 2 with domain accounts but only local admin, receiving the following Alert:
"The Trust Relationship between this workstation and primary domain failed."
I tried running the Power Shell tools on Exchange Server 2 to rejoing and to reset passwords for domain accounts as noted in some other blogs but no luck as the Server 2 could not make the connection with Server1 or other errors it kept spitting out.
I also during the investigation found the DNS settings were all altered on both the Server 1 and Server 2 which I luckily was able to change back to original because of inventorying it in the beginning when I started.
I need help figuring out if I need to rejoin the Exchange Server 2 manually by disabling the Certificate Authority Service (or removing the CA as listed here:
https://social.technet.microsoft.com/Forums/exchange/en-US/fb23deab-0a12-410d-946c-517d5aea7fae/windows-server-2008-r2-with-certificate-authority-service-to-rejoin-domain?forum=winserversecurity
and getting exchange server to launch again. (Mind you I am relatively fresh to server managing) Please help E-Mail has been down for a whole day now!

Exchange Server 2010 Backup and Restore

Hai,
I have Exchange server 2010 stand alone server combined with mailbox, hub and cas role. i dont have backup application program. I want to take my exchange database backup to my SAN storage automatically everyday...
Using windows server backup i can take full backup only and i can schedule it to happen daily.. Is it possible can i take incremental backup??????????for exchange 2010 database.
Thanks Chandru CT. MCITP

You have two basic options to backup Exchange 2010, VSS snapshots and "native backup" (meaning a Lag copy). As far as VSS backups go, there are three components; the VSS Writer, the VSS Provider, and the VSS Requestor. The Writer is built into
Exchange. In fact in Exchange 2010 there are two - the Exchange VSS Writer and the Exchange VSS Replica Writer. The provider can be a software VSS provider such as the Microsoft Shadow Copy provider or a hardware provider (usually supplied by your
SAN vendor. The requestor is what you would tend to think of as the backup application; it coordinates activities between the Writer and the Provider.
As far as the Exchange 2010 plugin for Windows backup goes, it a very minimal requestor. It only supports the Exchange 2010 VSS Writer, not the Replica Writer. This means you can only take backups of the Active copy of a database. The requirement
to backup the entire "volume" in the windows sense, or partition to the rest of us is a function of the way VSS works and is no real surprise. In fact, another limitation of VSS is that the logs and database need to be on seperate volumes: see
http://technet.microsoft.com/en-us/library/ee832794.aspx.
That it only takes full backups makes sense as well. Shadow copies, like many software providers and many hardware providers out there are copy on write. Initially, after the first one that is, they take up minimal space for some metadata.
As data is writen to the volume while the the snapshot is in place, the original blocks are evacuated to a "difference area" and the write is then written to the newly evacul\ated spot. You can generally put the difference area on the same volume or
somewhere else. The downside is to write a block while a copy on write snapshot is in place means a read and two writes for every write. This gets ugly on RAID 5 which already has a write penalty of 4; that turns into 9 IOs for every write while
the copy on write snapshot is in place. Since you can't do the snapshots on the replica because the replica writer isn't supported, that IO hit is on the active copy. When using copy on write snapshots, you generally want as few around as possible
for as short a time as possible; usually just long enough to export or copy the snapshot to another set of spindles. I really wouldn't want to use WSB plugin for Exchange 2010 in anything but the smallest deployments.
What about native backup? Well then you take a 100% space hit for every lag copy. In addition, restoring a LAG is a one shot deal. As you strive with the LAG to match what you could achieve with even daily or weekly copy on write snapshots,
the number of database copies, and Exchange mailbox servers, poliferates. You may want to consider a "Happy medium" that combines a LAG for fault tolerance/protection against logical corruption with copy on write snapshots (replicated or copied
to seperate storage) for HA. Perhaps DPM would be worth a look in your situation.
You did mention that you have a SAN. Most SAN vendors offer hardware VSS Providers. Many are copy on write, and you shift that set of problems to the, albeit likey a bit more performant SAN, Some vendors use other stratagies. The vendor
I work for uses allocate on write, so it avoids the 3 IOs per write copy on write penalty while a snapshot is in place. This means you can snapshot frequently and keep many of them around without penalty shortening your RPO and RTO. They optionally
archive truncated logs allowing for "up to the minute" restore of older snapshots, not just the last one. They also provide a proprietery version of RAID 6, called RAID DP that outperforms RAID 1. Combine that with all the storage efficiency features
like dedupe of primary storage, thin provisioning, compression, etc., that can all be combined and it starts to get compelling as the size of your deployment increases. Although I might be a bit biased when it comes to SAN vendors, if your SAN is someone
other than NetApp I still encourage you to talk with your SAN vendor and see what features/functionality they offer that can help you address your backup needs for Exchange 2010. I think you'll find much to like; it really comes down to scale and a cost/benefit
analysis.
If you decide that hardware VSS providers are not you thing and want to stay with a software vss provider, I encorage you to talk to the usual backup software vendors as well. Many can integrate with DAS and/or SAN, and have their own software
VSS providers often including support for the Exchange 2010 replica writer. This at a minimum allows you to snapshot passive copies. Features like replication (to get the changed blocks to other storage or off site), tape support (to roll backups
off to tape potentially to store off site) and catalogs come to mind as very useful things to have.
I'd take a look around at what's available and see if any of the things offered meet your business needs at a price you can afford to pay. The WSB Plug-in is a bare bones sort of thing, and it only gets better from there.

Send As, Send on Behalf and Full Access for Exchange server 2010/2013

[This FAQ contains 2 parts]
Testing and watching the behavior of Send As, Send On Behalf and Full Access permission.
Common issue and Troubleshooting on the three permission.
[Testing and Watching]
Based on following blog, I decide to test on my lab:
Full Mailbox Access Rights + Send On Behalf = Send As ?
http://blogs.technet.com/b/ehlro/archive/2012/04/06/full-mailbox-access-rights-send-on-behalf-send-as.aspx
Description on my lab and test:
Exchange 2010 + Outlook 2010
Exchange 2013 + Outlook 2013
Senders: A01, A02, … , A07, A08
Recipient: A09
A01 grand permission to other senders.
Two methods:
a. Use A0x’s credential configure A01’s profile, then send From both A01 and A0x via Outlook. Watching result in A09’s Inbox and Sent Items which has message copy left.
b. Use A0x’s credential configure A0x’s profile, then send From both A01 and A0x via Outlook. Watching result in A09’s Inbox and Sent Items which has message copy left.
Result as following forms:
1. Exchange 2010 + Outlook 2010 / Exchange 2013 + Outlook 2013
Using A0x’s credential configure A01’s mailbox, then send From both A01 and A0x
To A09.
2. Exchange 2010 + Outlook 2010 / Exchange 2013 + Outlook 2013
Using A0x’s credential configure A0x’s mailbox, then send From both A01 and A0x
To A09.
[Common Issue]
1. [Issue]
Exchange 2010 + Outlook 2010. A01 grand A03 Send As permission. However A03 can’t send as A01 to A09 and get NDR:
You can’t send a message on behalf of this user unless you have permission to do so. Please make sure you’re sending on behalf of the correct sender, or request the necessary permission. If the problem continues, please contact your helpdesk.
Details as following pic:
[Troubleshooting]
1) Based on the NDR, it seems a permission issue. Check Send As permission, however the Send As permission configured correctly. Pic as below:
2) ince the Send As permission configured correctly, it seems the permission hasn’t been replicated. Try to restart Microsoft Exchange Information Store service. It works.
Note: The Send As permission isn’t granted until after replication has occurred. Replication times depend on your Exchange and network configuration. To grant the permission immediately, stop and then restart the Microsoft Exchange Information
Store service.
2. [Issue]
Exchange 2013 + Outlook 2013. A01 grand A03 Send As permission. However A03 can’t send as A01 to A09 and get NDR:
Your message did not reach some or all of the intended recipients.
Subject: xxx
Sent: xx/xx/2014 8:20 AM
The following recipient(s) cannot be reached: A09
This message could not be sent. Try sending the message again later, or contact your network administrator. Error is [0x80070005-00000000-00000000].
Details as below:
[Troubleshooting]
1) Also check the Send As permission configuration first.
2) Then try to use A03 send as A01 to A09 via OWA. If OWA works well, it seems and issue on the Outlook client side.
3) This behavior may occur if the OAB in Outlook isn’t updated. Try to download OAB manually.
4) If doesn’t work, please close Outlook and try to delete all the OAB folder on your computer. The path of OAB folder in Win7, Win8 as below:
\Users\<UserName>\AppData\Local\Microsoft\Outlook\Offline Address Books
5) Restart Outlook.
Note: Be aware that you cannot send e-mail messages on behalf of a mailbox if the mailbox is hidden from address list. When sending a message, Exchange requires that e-mail address is resolved in the
From field.
3. [Issue]
Exchange 2010. A01 grant A0x “Send As” or “Send on Behalf” permission. A0x send as/ send on behalf of A01. The message is only copied to the Sent Items folder in A0x’s mailbox (same as the result of my test). Also cannot configure Exchange 2010 so that the
message is copied to the Sent Items folder of both A01 and A0x.
[Troubleshooting]
This issue occurs because Exchange server 2010 was designed to copy message to the Sent Items folder of the sender only. This issue can be solved by installing Exchange 2010 SP2 UR4. More details in the following KB:
Messages that are sent by using the "Send As" and "Send on behalf" permissions are copied only to the Sent Items folder of the sender in an Exchange Server 2010 environment

Nice guide Mavis, I recently explored the same topic. Few things you might want to add is the type of connectivity (Cached vs Online will produce different results) and to expand further on the methods of adding the other mailbox in Outlook (additional mailbox
vs additional account defaults to different methods). Check the screenshot:

MS Exchange server 2010 messages will be placed in the poison queue and the transport service will crash

Can any1 please help.
We have Exchange server 2010, we just upgraded it with SP3 and then the issue occers that we were unable to send n receive mail outside of our LAN...i mean from gmail or hotmail..
we have then updated with CU4 which is the latest but still messages will be placed in the poison queue and the transport service will crash.
We have disabled the antivirus also but issue remains same.
We have CAS 1 n 2 as of Clustering environment and we upgraded sp3 for both. but we did CU4 on CAS1 to see the results to resovle this issue but no luck

Hi,
Did you get any NDR message now when you send a email to outside? And vice versa.

Trouble Connecting iPad and iPhone to Exchange Server 2010

Exchange Server 2010.
I have found some online instructions for connecting iPhones and iPods (or iPads) to Exchange Server 2010 using activesync. I enter all the information as I understand it (the same info used to successful connect Droids), and I do not get an error
until I try to sync (retrieve mail) the first time. Then it says, "The connection to the server failed."
In the instructions I follwed it has this statement, "Before we get started, please be sure your administartor has purchased you an Activesync license and assigned to
your email address." What the heck does this mean and how can I accomplish it? I know activesync is working. So why do I need a "license"?
Any help will be appreciated.

CUCM 7.1.2 and Exchange Server 2010

Hi,
I have a cucm 7.1.2 installed and configured and an exchange server 2010 box as mail server on another system.
If I want to send voice mail from Cisco IP phone through the cucm to the exchange server, do I need an external voice mail like Cisco Unity, or the cucm should have everything I need.
Thank you!

Hi -
If you want to use Exchange 2010 as your voicemail system, you need an Exchange server hosting the Unified Messaging server role. Microsoft has specific requirements for using Exchange unified messaging as well as licensing for your voicemail subscribers. Here is a good review - http://technet.microsoft.com/en-us/library/bb125141.aspx. Plus there should be an integration document for voicemail functionality, I found the CUCM version 7 integration doc here - http://www.microsoft.com/downloads/en/details.aspx?FamilyID=d5db0297-7850-4f52-b965-b8006b4c05f5&displaylang=en
