Duplicate Roomlist's in Exchange / Outlook 2013

Hey guys, any idea why I have two of the same Roomlist's now populating in Outlook 2013?
I added the list, and all looked fine, but for some reason (maybe recent contacts or something) I'm seeing two... any way to fix/prevent this?
FYI we're running Exchange 2013 CU4 I believe..

Hi,
From your description, I recommend you check if this issue occurs for others. If the issue only occurs for you, I recommend you create a new profile and check the result.
If the issue persists, you need to go into the registry, locate to: HKEY_CURRENT_USER/Software/Microsoft/Office/15.0/Outlook/preferences. There is a string called RoomFinderRecentRoomList, delete this entry and then restart Outlook and check the result.
Note: Please do a backup before deleting it.
Hope this can be helpful to you.
Best regards,

Weird/Complex Exchange/Outlook 2013 Issue

I posted this in the Outlook forum but I was given the recommendation to post it here so I thought I would see if anyone could help.
So we have a client that is creating Outlook calendar events in Outlook 2013 who is running on Exchange 2007 running on a SBS2011 server. In the body of that message they are putting tons of text in it [primarily it is how they are communicating about
the events]. Some users see all the text and some don’t either on their iPhone or in Outlook 2013. They are all using the same version of Outlook. We were told that the mailbox could be corrupted [I don't think so because nothing else is affected]. Another
person stated that Microsoft only allows a certain number of characters in the body of the calendar appointment and this issue is not resolvable. Does anyone here have any ideas as to what could be the problem and if it is truly unresolvable?
Any help is greatly appreciated!

Hi Cale,
Does the problematic user see all the text via OWA?
I also recommend you try the following methods to troubleshoot the issue:
1. Change the problematic user's PC and use a normal user's PC to check if there is the same issue.
2. Try moving the problematic mailbox to another database and check if any helps

Exchange Outlook 2013 freezes when deleting shared calendar for employees who have been removed

Hi,
I am removing users' shared calendars from my outlook 2013 in exchange environment. The problem is, that the shared calendars belong to users who have left the company and have been removed from the domain, this is causing outlook to freeze because i think
it's trying to find the entry then delete it, rather than delete it.
There is no problem deleting a shared calendar for an user who still is in the domain. This seems to be strictly affecting users who have left the domain.

Hi,
Generally, if the shared calendar owner is removed from the Exchange environment, the shared calendar which was added before should be removed from Outlook client normally.
Please use Outlook with Exchange cached mode, and make sure the shared calendar was not added in Advanced tab in Account Settings. Please start Outlook in safe mode and remove the shared calendar to have a try.
If the issue doesn’t happen in safe mode, please disable the third-party add-ins one by one to find out the cause.

Office 365 hosted Exchange Outlook 2013 "The resource you are trying to use is located on an unsupported version of Microsoft Exchange"

I have Outlook 2013 downloaded from my Office 365 account and am getting the error "The resource you are trying to use is located on an unsupported version of Microsoft Exchange". I have added all the steps I have followed so far below.
We changed over to the Office 365 hosted Exchange from 2003 Small Business Server yesterday. I have backed up my Outlook 2010 then uninstalled all Office applications and rebooted.  Then downloaded the Office 2013 suite from my account
and installed it.  Ran the desktop setup to "Set up your desktop applications to work with Office 365."  Went to the control panel and launched the mail tool, made the
profile and named it Outlook and it auto filled with the correct info.  Clicked Next and it all checked as good, but when I launch Outlook I get the error "The resource you are trying to use is located on an unsupported version of Microsoft
Exchange". I have rebooted the laptop and recreated the account three times with the same results.
Any suggestions?

OK. So we solved the problem. At least in my case.
We deleted the profile again then jumped on a neighbors wifi and then ran the desktop setup from Office 365 again. Then we launched the mail setup tool, created a new profile and entered the information for the account. After this took we launched
Outlook and everything is working fine.
One thing to point out is that prior to the time that it worked, when I would create the profile and open it to set it up, it would auto fill the two available fields Name and Email Address. On the last run it didn't auto fill and I had four fields
to fill out. Name, Email Address and Password (x2).
Hope this helps someone.

Exchange/Outlook 2013 No free/busy information could be retrieved

We are getting a problem for certain users where their Free/Busy info is not visible in the Scheduling Assistant.
HOWEVER - the same user's calendar can be viewed as a Shared Calendar without a problem.
I believe this has been working previously and has now stopped.
It is affecting Mac & PC user the same and is also apparent in OWA.
Please help as typically this is affecting our VIPs.
Thanks

Hi,
According to your description, I noticed that the free/busy information also couldn’t be retrieved in OWA. Please confirm your Exchange version and double check whether all users can’t use scheduling assistant to view free/busy information.
In Outlook client, please run Test E-mail AutoConfiguration tool to test the Autodiscover service and Availability service URL:
please open Outlook - press CTRL key - right click on the Outlook icon from right bottom corner taskbar - Test Email AutoConfiguration. Put your email address - uncheck use guessmart and secure guessmart authentication - click Test to check your Autodiscover
service.
In Results tab, please get the Availability service URL. Then access it in Internet Explorer in your local machine, and check whether a proper XML file can be returned.

Delay or schedule sending email messages Hosted Exchange Outlook 2013

Hello,
Hopefully I am posting this question in the right place.
We have a user that is trying to delay a message to a different user. The problem is that if the original user who is trying to delay the message closes outlook the delayed message will not go out to the intended recipient. I did notice the KB for
office:
https://support.office.com/en-us/article/Delay-or-schedule-sending-email-messages-ea346137-e1e2-4ec4-a77b-1522b75b15d1?ui=en-US&rs=en-US&ad=US
And it does state that "If you are using a POP3 or IMAP account, Outlook must remain open until the message is sent"
My question is,
We actually have a hosted exchange account with outlook. is that the same as pop3/imap accounts therefore the outlook client needs to stay open?
Will the delay option work in OWA?
What about rules set in outlook to forward to other individuals, does outlook the application have to stay open?
Thanks all for any help/feedback

Hi,
For your first question, delayed delivery options are client side in cached mode and server side in online mode. So, when using
Cached Exchange Mode, Outlook must be connected and open at the assigned delivery time for the delayed delivery message to be sent. If you are using
Online Mode, then you don't need to leave Outlook running.
As far as I know, we don't have the same delayed delivery option in OWA. And also, only rules can be created for
incoming emails with Outlook Web App, therefore a rule to set a delay on outgoing email is not possible.
For the rule to forward an incoming email automically, you'll have to use the "defer" rule, but as far as I know, it's a client-only rule, will only process when Outlook is running.

Cannot recieve email in Outlook 2013 Inbox

Set up Exchange Outlook 2013 email. Everything worked in the setup, however Outlook will only send but not receive inbox messages. Set up in Windows Mail and Apple phone and all is good. Only Inbox messages in Outlook not working.
Any suggestions?

Hi,
According to your description, I understand that outlook client can send but not receive messages.
I want to double confirm some points, please help me to collect answers to following questions:
1.How is the impact , one user or all users?
2.Cannot receive internally or externally?
3.How about receiving by using OWA?
4.Any error messages when cannot receive?
If OWA works fine, this indicate that an issue on the Outlook client side.
Please check whether the messages exist in the Junk E-mail folder. If yes, please re-configure the Junk E-mail Filter.
Please run Outlook safe mode to avoid some AVs and add-ins, or re-create profile for testing.
Please Send/Receive all Folder or Update Folder in Outlook.
Also try to collect related error message for the further troubleshooting.

Outlook 2013 - cannot use RoomLists and Suggested Times

Hi,
maybe someone has a clue on what is wrong here.
In OWA, we can use the new features RoomList and Suggested Rooms when using the Calendar Assistant to plan a new meeting. The room list can be first be chosen, and the fields for the rooms are then populated as expected, you can choose one of the rooms.
The following is true for every Outlook Session on PCs/virtual Clients, they are configured to use Online Mode: In Outlook 2013, when using: New Meeting - Scheduling Assistant, the feature "Choose an available room" stays complete empty and
does not show the room list. Also the box below that, labeled "suggested Times", does not load or display content. Instead, an error message is displayed in it: "Suggestions cannot be provided because free/busy data could not be retrieved."
Laptops use the exact same Outlook version, but run in cached mode. Here, if you deconfigure "Communication using http" in the OL profile, the lookup for suggested times works _once_ until Restart, then the button is automatically added, the
profile automatically made good again, and the suggestion function is broken again.
If you deconfigure the button "Connect to Microsoft Exchange using http" in the Outlook Profile under the connection tab on an _online mode PC_, the profile is broken and not automatically made good again. So no temporary workaround is possible
here.
We do not run policies that may keep Outlook 2013 from using the functions. In fact we do only rule cached or online mode.
Our Room List is free of special characters and short enough, so no problems that other people have found in their environments.
We have found some older articles reporting broken functionality, when applying or not applying hotfixes. We have checked several of that and it is not the source of our problem.
Also, we are currently within one domain, so no complicated setup using one or more forests or even other domains, configuration of free/busy accounts should not be an issue here.
Our best guess is it may have to do with using Exchange webservices or MAPI for the connection, see both ways described communicating over http or not above, but we have not found an error or wrong configuration here.
Can you please advise on where to search next?

Hi,
Which version of Exchange server are you using?
Does the free/busy information display correctly if we click the Rooms button and select a room from GAL?
Are you trying to start a meeting in which either the Start time or the
End time is outside your working hours? If this is the case, this issue may happen. Please have a look at the following KB article and check if it applies:

Outlook 2013 sending duplicate emails to my Blackberry

I have spoke to Blackberry and Microsoft tech support but neither could find a solution. I have several email accounts on my PC running Outlook 2013 and on my Blackberrry Q10.
First, I receive an email on my BB. Then, I also receive a duplicate on the BB once I turn on the PC and connect to wifi. It can be many emails that come in all at once, all duplicates.
This does not happen, however, with every email account. I have several inboxes in Outlook, and it only happens with the email accounts that are associated with one of the inboxes.
That particular inbox is associated with a Microsoft Exchange server, but it does not happen with the Exchange account. I only get duplicates of emails from every account under that inbox.
Please help, thanks!

Hi,
What is the type of account configured in Outlook and Blackberry (POP3, IMAP or Exchange/MAPI)?
If you happen to have another smartphone (like an Android phone) around you, I'd suggest you have a try on it. This way, we'll know if Blackberry is the problem here.
I've just came across this thread in Blackberry support forum, it's well worth a look. Blackberry users had a thorough discussion on this issue:
Duplicate emails in BB inbox after using Outlook (Please Note: Since the web site is not hosted by Microsoft, the
link may change without notice. Microsoft does not guarantee the accuracy of this information.)
Here is a KB article from Blackberry Knowledge Base, which listed out few causes and related resolutions for the issue of duplicate emails on the BlackBerry smartphone:
http://btsc.webapps.blackberry.com/btsc/viewdocument.do?noCount=true&externalId=KB13528
(Please Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.)
Please take a look and see if any of the resolutions work for you.

Exchange 2013 CU7 - Frequent Outlook 2013 Disconnections and Delays

We currently have the following environment:
Windows 2012 VM on Hyper-V with 24GB of RAM and 4 virtual procs (1 socket)
Cisco UCS, B200 M3 Blades
Exchange 2013 CU7
Exchange 2007 is in our environment, but public folders have been removed and only a few stale, unused accounts exist on it.
Two dual-role CAS/Mailbox servers
Mailbox servers are in a DAG
MAPI/HTTP is our connection protocol
.NET Framework 4.5.2
Clients are Outlook 2013 SP1 on Windows 7 and 8.1
(Currently round robin DNS, but we have a hardware load balancer we've temporarily taken out of the mix to solve this problem)
What we're seeing is frequent disconnections from Exchange, regardless of the CAS server. That is, both CAS servers will disconnect clients, but not at the same time. When we look at the Exchange boxes, we notice that the CPU is 99% - 100% each time the
disconnections occur. When we hunt down the IISWorker process causing the sudden CPU run, we see it comes back to the following app pools:
MSExchangeMAPIFrontEndAppPool
MSExchangeMAPIMailboxAppPool
(We were running RPC/HTTP, but switched to MAPI/HTTP to resolve the problem. We had the same issue with equivalent RPC app pools at the time.)
Eventually, within a minute or two, the CPU load will decrease and the clients connected via that CAS will regain connection. As you can imagine, the pain is felt more frequently by uncached clients--although everyone, regardless of caching, will see
the disconnections.
Basically, the problem sounds exactly as shown in this KB: http://support.microsoft.com/kb/2995145 Unfortunately, we already had .NET 4.5.2 installed, and have changed the environment variable and registry as shown in the article.
We're in contact with Microsoft Support, but thus far they're scratching their heads.
I'm clearing up all small errors to decrease the noise in the application error logs, but the most persistent one is Event ID 106 (MSExchange Common):
"Performance counter updating error. Counter name is Time in Resource per second, category name is MSExchange Activity Context Resources. Optional code: 2. Exception: The exception thrown is : System.InvalidOperationException: Instance 'ad-powershell-defaultdomain'
already exists with a lifetime of Process. It cannot be recreated or reused until it has been removed or until the process using it has exited."
Loading/reloading and recreation of the performance counters does not fix the problem, by Microsoft Support or us. Of course, this error existed before we started having issues; I'd just like to clean it up just in case it's a contributing factor.
Has anyone seen anything similar?

We're using a Barracuda load balancer (641), but we've eliminated that as a source of the problem. The CPU spikes and disconnections happen whether or not the load balancer is in use.
This problem is still ongoing, and we're still working with Microsoft Support. Right now they're focused on our environment, but having combed through it numerous times, there's nothing that stands out. I suspect this is a bug in CU7 (yet I would
readily accept our environment being at fault if it means we can identify and resolve the problem), but that's not the road Support is going down.
We've looked at storage I/O on the VM hosts (disk responses are 10 MS or less), added double the CPUs to each mail server (for a total of 8, each), disabled TCP chimney offload, run numerous Experfwiz log collections, etc... Now
the tech is focused on a particular mailbox database being the culprit because it also takes up more CPU when the MAPI app pools are gunning pretty high. I suspect that it is a symptom and not the problem, but I have no choice but to follow his lead.
What is your environment like? Are you also CU7? And did the problem show itself after a cumulative update was applied?

Fully automated Outlook 2013 with Exchange 2010 client setup

Hi,
I'm trying to create a situation where a user fires up Outlook 2013 for the first time and the Exchange account is configured for them without any intervention whatsoever.
I currently have it that when a user opens Outlook, they see the "Welcome to Outlook 2013" screen and they click next. They are asked if the want to setup Outlook to connect to an email account and click Next. On the next screen, there
primary SMTP address is automatically filled out, and then autodiscover takes over and configures the rest for them.
I have configured AutoDiscover correctly (including SCP), and configured a GPO with "Automatically configure profile based on Active Directory Primary SMTP address".
However, I still get that "Welcome to Outlook 2013" screen.
How do I get rid of that to make the whole process fully automated?
Many thanks,
-Mark

Hi Mark,
I have this issue before.
When we first add our accout to Outlook, we should better create a new profile manually.
I suggest removing our accout from Outlook via "Mail" and re-creating new profile.
Operation details as below:
1. Start-->Control Panel-->Mail-->E-mail Accounts...-->select your account and Remove it-->Close
2. Show Profiles...-->Add-->then configure your account again.
Hope it is helpful
Thanks

Can't move "completed" items into folders using Outlook 2013 on a Microsoft Office 365 Home Premium Account using a work Exchange 2010 address

I've been in touch with several Microsoft support teams about this issue, and the latest move was to shove me off onto Pro support, but since I'm using a personal Office account, I'm hoping that through the community I can find a way to resolve this issue without
escalating through our IT department. I do not think this is an Exchange issues because I have previously used this product and method without resulting in this error on a Windows 7 32-bit AMD computer and a Windows 8 and 8.1 Professional 64-bit Intel computer.
Here's my current specs:
Windows 7 Professional 64-bit, service pack 1
AMD A6-5400 3.6 GHz
8GB RAM
Microsoft Office 365 Home Premium
Office updates automatically, version 15.0.4551.1512
About Outlook shows "Microsoft Outlook 2013 (15.0.4551.1511) MSA (15.0.4551.1508) 32-bit/Part of Microsoft Office 365 Home Premium"
Here's how to reproduce the issue:
1) Open View Settings
2) Select "Other Settings..."
3) Disable "Use compact layout in widths smaller than XX characters" and enable "Always use single-line layout"
4) Select "Columns..."
5) Under "All Mail fields" add "In folder"
6) Select any email
7) Context-menu -> Find Related -> Emails in this Conversation
8) Select "more"
9) Sort by folder
10) Select all messages from Inbox.
11) Use Outlook's preset "Done" function and select a destination folder
12) Watch Outlook fail to run "Done" and reset your UI without producing an error.
The first attempt to resolve this issue was to set up a new Outlook profile. This seemed to exacerbate the problem and resulted in Outlook providing an "Unknown error" before resetting the UI.
The second attempt to resolve this issue was to run "outlook.exe /resetnavpane". However, the nav pane does not appear immediately relevant to this issue.
The following similar steps also result in a crash, this time with an error:
11) Flag all select message as Complete.
12) Move all messages from Inbox to a destination folder.
This change in procedure results in the error "Cannot move the items. Some items cannot be moved. They were either already moved or deleted, or access was denied."
Help me, Microsoft Community. You're my only hope.

Import the calendar and contacts in Outlook.com. For contacts, export from Outlook as csv and import into Outlook by choosing the Other option (https://people.live.com/import/other?biciid=ImportCatalog)
You'll need to save the calendar as an ics file to import it. Select the calendar folder, the File, Save as an save as an ics.

"The Connection to Microsoft Exchange is unavailable" when adding second Exchange account to Outlook 2013

I have a problem that I've found to be typical, just haven't found anything that describes my exact problem.
I'm having trouble adding a second Exchange 2010 server account to Outlook 2013 in one of the computers of the domain. Outlook 2013 will complain with "The Connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete
this action".
I've Googled and found many threads with the same error... however most of those seem to be either a problem with the server, or the Global Catalog in Active Directory, or the "connection method" (I've tried all found solutions to no avail).
This is not the case, since the first account is added with absolutely no problem. It can send and receive and I can delete the outlook profile and recreate it and it'll give no problems. I have this problem only when adding a second account.
This is a fresh Windows 8.1 install with an up-to-date Outlook 2013. I have other computers in the same domain and network, with the same setup (Win 8.1 + Outlook 2013) configured with two exchange accounts with no problem.
There are no connectivity problems, I can access that same account through OWA and in other computers on the network... the Global Catalog seems to be fine (shows two active DCs, which is correct).
I've tried deleting and recreating the outlook profiles, repairing the outlook installation, even deleting all outlook files in AppData and letting it recreate them, with no success.
Any hints of what could be going on?
Before I speak, I have something important to say.

Hi Javier,
Thank you for the update.
I have tested on my lab and get following result.
Lab: Exchange 2010, CAS Array (CAS01+CAS02), MBX01, DC
Type Server Field
Check name result
Changed Server Field
CAS01.domain.com
Yes
CASArray.domain.com
CASArray.domain.com
Yes
CASArray.domain.com
DC.domain.com
Yes
CASArray.domain.com
MBX01.domain.com
No
"The Connection to Microsoft Exchange is unavailable"
Based on my knowledge, the reason why inputing DC FQDN in the Server Field fixes this issue is that Outlook performs AD Lookup and finds the account configuration from AD, then back the CAS Array FQDN in the Server Field instead of DC FQDN.
Exchange 2010 is different from Exchange 2013, if you are using Exchange 2013, we need to input MailboxServerGUID.domain.com into Server Field.
If there is anything I’ve misunderstood, please don’t hesitate to let me know.
Thanks,

Outlook 2013 won't start with Exchange 2003 on the network

Hello All,
I have outlined my problem below, If someone could please help me that would be great!
Environment
==========
SBS 2003 Server Running AD and Exchange 2003
Clients are Windows 7 with Office 2013 and Outlook 2007 (to connect to existing 2003 Server)
Issue
=====
I am in the process of Migrating off of SBS 2003 to Office 365. The situation is that my customer needs to keep the SBS 2003 server until end of life where they will at that time determine a upgrade path. They however do not want to use Exchange
anymore. I have migrated their mailboxes successfully to Office 365.
The problem that I am running into is with Outlook 2013. Because Exchange 2003 server still exists in the network I am unable to launch Outlook 2013. I get a Message
"The Resource that you are trying to use is located on an unsupported version of Microsoft Exchange Contact your e-mail administrator for assistance"
I have tried to create a new Outlook profile. However since the exchange server exists still it auto discovers the server for the account.
Questions
========
1. What is the best workaround for this situation? My customer still needs to keep their SBS sever for their domain and plans on retiring the server before Server 2003 End of Life this coming server. (Upgrade is not an option, nor is getting
rid of the Domain, they are a small company).
2. If I disabled the Exchange services on the server would this work? Would outlook 2013 not detect Exchange
2003 on the network?
Basically I need to force Outlook 2013 to look at Office 365.
3. Configuring Outlook 2013 to manually connect to Office 365? The problem here is that how do I locate the server name for the manually connection? I have found some blogs that say to use Remote Connectivity Analyzer https://testconnectivity.microsoft.com/
but I cant seem to get that to work.
Any ideas?
Thanks!

Hi,
Please refer to the following article to check your migration steps from Exchange 2003 to Office 365:
http://blogs.technet.com/b/canitpro/archive/2013/05/31/step-by-step-migration-of-exchange-2003-server-to-office-365.aspx
If all mailboxes are moved to Office 365, Outlook 2013 would use Autodiscover service to connect to your Office 365. Please make sure your Autodiscover service is configured correctly in Office 365. Also
verify that all the DNS records and Public Folder are updated and pointed towards Office 365 services. If there is any question about migration to Office 365,
we can ask a question in Exchange Online forum for more suggestion:

Outlook 2013 randomly loses connection to Exchange 2007 server

Hello everyone,
I have received complaints from some of our users over the past couple of months about them not receiving mails or about sending mails which do not get delivered. A little bit of investigation into the matter showed me that Outlook 2013 had lost its connection
to the Exchange server. (Which is Exchange 2007 SP3 running on Windows Server 2008 / SBS2008, in case it matters.)
Which is bad enough in itself - none of our users running Outlook 2007 and 2010 had that problem - but it also does so in a rather inconspicuous manner, so the users did not notice. Closing and restarting Outlook helped every single time, but the users did
not notice when this happened, and telling them to just restart Outlook every hour or so does not seem like an overloy practical idea.
All of the clients encountering the problem are running Outlook 2013 on Windows 8/8.1 Pro. We do not have any clients running older versions of Outlook on Windows 8, so I cannot tell for sure if this problem originates in the OS or if it is an Outlook problem.
The first couple of times I encountered the problem, it was on laptops, so I suspected some power management issue initially. I made sure Outlook connected to the server via HTTPS, which it already did. Then I did not hear of the problem for about two months,
but recently, two of our users have run into the problem again, and while these were still Windows 8.1 machines, running, of course, Outlook 2013, they are plain desktop computers, not laptops, and I already toned down their power management settings, so I
do not think that it has to do with the problem.
Has anybody encountered a similar problem or even - more importantly - a solution? This problem is really frustrating, because our users are very sensitive to problems with their email, and the fact that this problem only occurs randomly and - all in all
- rather rarely, makes it very hard to track down.
Thank you all very, very much for any insights you might be able to share with me!

Hi,
Please ensure that Outlook 2013 clients retain their connection with the Exchange server using HTTP:
Have the Outlook 2013 user check the settings under FILE -> Account Settings -> Account Settings -> E-mail tab -> Select the account and click Change -> More Settings -> Connection tab -> Exchange Proxy Settings -> Make sure both
"On fast networks, connect using HTTP first, then connect using TCP/IP" and "On slow networks, connect using HTTP first, then connect using TCP/IP" are selected -> OK.
