Impact of enabling Calendar Repair Assistant on Exchange 2010 mailbox server

We have a couple of iPhone users reported they were having calendar items disappear from their calendars. Many suggest to enable Calendar Repair Assistant for those users on mailbox servers. We are running Exchange 2010 SP2 RU7. Do
you know if there's any impact like performance when enabling Calendar Repair Assistant ? What's your best practice? Thanks in Advance !!

Hi,
The Calendar Repair Assistant is used to detect and correct inconsistencies with single and recurring meeting items for mailboxes located on the Mailbox server. Then recipients won't miss meeting announcements or have unreliable meeting information. Based
on my knowledge, there is no official article mentioning that enabling Calendar Repair Assistant has an impact on performance.
Hope my clarification can be helpful to you.

Exchange 2013 CAS server connection to Exchange 2010 Mailbox server

Hi Guys,
I have a quick question i am planning to upgrade my infra from Exchange 2010 to Exchange 2013 and i have come across a small question, my infra looks likes below
3 Exchange server (CAS+ HT + MBX roles) Exchange 2010
1 Exchange server MBX role For journlaing Exchange 2010
1 CAS for internet owa access Exchange 2010
Now i will be installing exchange 2013 CAS on 2 box and MBX on 3 box
will decomm the 3 exchange box which has (CAS+ HT + MBX roles) and 1 CAS which we use for owa access.
will keep the Journaling server as it is will not be decomming it as of now.
My question is is will i be able to connect to the journaling mailbox's which are hosted on exchange 2010 journaling server without actually having any 2010 cas server, will exchange 2013 cas directly help me to connect to the journal mailbox or would i need
to add CAS role on Exchange 2010 journaling server and enable outlook anywhere configure the directories with the url's to make it working.
Please suggest on the same.
BR/Deepak

Hi TheLearner,
Thank you for your question.
Exchange 2013 didn’t connect to the journal mailbox directly when we access it by outlook/OWA. The journal mailbox will connect the former Exchange 2010 CAS. Or we could migrate Journaling mailbox to Exchange 2013. Because Exchange 2010 could communicate
with Exchange 2010 by RPC, but Exchange 2013 could communicate with Exchange 2013 by HTTPS.
If there are any questions regarding this issue, please be free to let me know.
Best Regard,
Jim

Hi Team,
We have 4 Mailbox server role with below configuration. CAS/HT is installed seperatly on different server. How do I calculate the RAM required for the system. System Configuration --
HP Proliant BL460c /Dual Processor (Hexa Core) /95GB RAM.
No of users hosted on the server 6200, No of Active/Passive Database copies on server -- 8. No of Mails Sent/Recived/Size on daily basis (Avg) - 22422/6344/13075. Do we have any formula to calculate the RAM to be installed on the server.

Exchange 2010 Mailbox server role now showing in EMC

Hi,
I am installing E2K10 standard edition in my lab and installed CAS + HUb role on a machine with OS Win2K8 SP2. Now I installed MBX role which I did on Win2K8 R2. Installation was successful with no error but I am unable to see mailbox server in EMC and
unable to create database while it is showing in Adsiedit. So I am confused if the issue is because of mismatch of OS on both machines? Is there a way I can do some changes in Adsiedit so tht newly installed machine can start showing in EMC or should I uninstall
it and build the same machine with OS Win2K8 SP2 ? Thanks.

Do you get Mailbox Server when you run these commands?

Outlook 2007 Clients Cannot Access Free/Busy Calendar info. for Exchange 2010 Mailbox

Hi:
I have Outlook 2007 clients that cannot access Free/Busy Calendar info. for Exchange 2010 mailboxes. They receive error like "...you do not have appropriate permissions..."
If those same users logon to a machine running Outlook 2010 then they can view the free/busy info. of the other user's mailbox, so I believe the permissions are set correctly on the mailbox to allow the viewing.
Any insights are greatly appreciated!
Thank you!
Bob Herman IT Tropolis

Hi Herman,
As you said, it seems users have proper permissions on mailbox.
Please make sure users has Reviewer permission on Outlook 2007.
Please try to run Outlook 2007 under safe mode or re-create profile.
Also try to turn Outlook 2007 to Exchange Online mode from Cached mode.
Thanks

How to monitor particular individual Exchange 2010 mailbox

Hi
Is it possible to monitor a particular individual Exchange 2010 mailbox? If so please send me the script or steps to to accomplish this
Donald D'souza (http://donald-scom.blogspot.com/)

The Exchange 2010 MP has had some issues of late and is once again unavailable. Hopefully this should be rectified soon. Keep an eye on the Management Pack forum and someone should post there once it is back.
I appreciate the Exchange team are looking for ways to get extra monitoring from SCOM and I'm certainly not saying you can't do mailbox monitoring with SCOM. I'm just saying be careful. I have seen one enterprise write a discovery to discover the
mailboxes they wanted to monitor. The discovery captured data that changed every iteration that the discovery ran. They then wondered why SCOM stopped working, ignoring the fact that they had discovered thousands of objects whose properties changed every
time discovery ran, causing huge numbers of state change events and massive database growth.
If you are looking for in-depth exchange mailbox monitoring then SCOM is not the tool for it. Quest and Sirana do dedicated enterprise tools. If you take a look at the links and say that is what your team want then I'd suggest evaluating those
products. Developing SCOM to deliver that would not be cost efficient.
Hope you don't mind but I'll ask again - what specifically do you want to monitor? Mailbox Size? Number of emails sent \ received? size of message sent? destination? number of attachments? size of attachments? blocked messages? If you need deep detail
along the lines of the following then you really need to evaluate the following:
http://www.sirana.com/exchange/reporting
If you end up writing scripts to do all the above then you will likely severely impact performance of either SCOM or your Exchange server or possibly both.
Sadly (for budgeting) SCOM doesn't necessarily replace specialist tools - it just complements them. Likewise, if you want deep dive SQL then you'll still need Quest or Idera based tools. Probably fewer licenses and better targetted at servers with known
issues.

Auto-Mapping Exchange 2013 Mailboxs in an Exchange 2010 Mailbox

We're in the middle of migrating mailboxes from Exchange 2010 to Exchange 2013. Many of our users have Auto-Mapped mailboxes as well. In my testing, I've found that I cannot Auto-Map a mailbox that's on Exchange 2013 in a Exchange 2010 mailbox. I can manually
add it and it works fine. Is this by design with this type of coexistence or is there a fix for it? Our current Exchange 2010 environment is at SP3 with UR2.
Orange County District Attorney

This issues is fixed in UR5 so suggest you to upgrade Exchange 2010 to SP3 UR5.

Exchange 2013 / 2010 co-existence - Outlook won't connect to Exchange 2010 mailboxes

Greetings! I have a lab set up at home where I have been testing co-existence of Exchange 2013 and 2010 for a future corporate upgrade project.
I am running into some odd behavior. Any mailbox that has been migrated to Exchange 2013 works just fine, however, when I try to set up Outlook for a mailbox still on Exchange 2010 I receive errors. OWA works just fine for these Exchange
2010 mailboxes, it is just Outlook that has the problem. This is what I am running into:
1. Outlook uses autodiscover to locate server settings. It fails at the 'logging on to mail server' step saying that Exchange isn't available; Outlook must be connected, etc.
2. It then gives me the settings box for Exchange server and Mailbox. This is auto populated with one of the Exchange 2013 servers (there are 3 of them, all have both MBX and CAS role). If I then change the server to the Exchange 2010 CAS server,
and hit 'check names', it underlines the very same entries (like it found them this time) that were there initially and goes on to finish the configuration.
3. When I launch Outlook with this Exchange 2010 user, it fails to open with the error message that the set of folders couldn't be opened.
I've been doing as much research on this as I can. I've tried disabling IPv6 to no avail. It seems as if perhaps the issue is with Exchange 2013 proxying the request back to the Exchange 2010 servers but I am not sure what to check in that regards.
Any suggestions? Thanks in advance!

Hi,
Don´t disable IPV6 on an Exchange Server, it is, in my opinion not necessary - also applies for AD.
You can use your original SSL Cert for your new Ex 2013 environment.
In dns you want two host A records: mail.domain.com and autodiscover.domain.com
On your 2013 set your internal and external virtual directories to mail.domain.com
leave autodiscover and Powershell alone.
Also set the autodiscover URI to your Certificate name ie. mail.domain.com
Set-ClientAccessServer -Identity "YourCASServer" -AutoDiscoverServiceInternalUri "https://mail.domain.com/autodiscover/autodiscover.xml"
Thanks. I wanted to give some additional info before I run any commands. I currently have an A record for autodiscover and it is pointed to the Exchange 2013 DAG/cluster IP. I have a 3 entries for mail.domain, for DNS round robin; basically
it is listed 3 times for the IP of each of my Exchange 2013 servers. Does any of this sound problematic?

Exchange 2010 mailbox prompts for authentication to Exchange 2013 mailbox

I am in the process of a 2010 to 2013 migration. The only issue I can't seem to manage is an authentication issue with Outlook 2010. My Outlook profile consists of my Exchange 2013 mailbox and a shared mailbox on Exchange 2010. Initially, Outlook was prompting
for authentication to the Exchange 2010 mailbox. Regardless of whether I entered the correct credentials or simply cancelled the prompt, I still had full access to both mailboxes (including Public Folders on 2010). The authentication prompt was removed with
the following command:
Get-OutlookAnywhere -Server my2013exchserver | Set-OutlookAnywhere -InternalClientsRequireSsl $true
The second issue I now have is the reverse of the above: an Exchange 2010 user is prompted for authentication to an Exchange 2013 mailbox. How do I begin to troubleshoot this problem - should I run the same command (above) on 2010? I don't quite understand
how Outlook communicates with Exchange but I am thinking there is an incorrect setting on one of the Virtual Directories(?).
Many thanks.

Hi Dennis,
Please open Outlook - press CTRL key - right click on the Outlook icon from right bottom corner taskbar –Connection Status to check the connection for your Exchange 2010 mailbox with shared 2013 mailbox. The following example in my test results:
Please check your connection authentication. We can run the following command to set your Outlook Anywhere for Exchange 2013:
Set-OutlookAnywhere -Identity "E15-01\Rpc (Default Web Site)" -InternalClientAuthenticationMethod Ntlm -ExternalClientAuthenticationMethod Basic -ExternalClientsRequireSsl $True -InternalClientsRequireSsl $true
In Outlook side, please ensure the following settings in Account Settings:
In Security tab, make sure Always prompt for logon credentials is unchecked and Logon network security is set to Negotiate Authentication.

Moving Exchange 2010 Mailbox replicated databases path in DAG environments.

Hi there,
I’m trying to get some feedback on the topic of moving Exchange 2010 Mailbox replicated databases path in DAG environments.
Here is the situation: I currently have a 3-Node DAG (Node 1 and Node 2 are in my main datacenter, and Node 3 in my Disaster Recovery (DR) site in a remote location.
I have DB copies in Node 2 and Node 3. The thing is that the DB copies in Node 2 are in an older storage box and since we got a new storage box, I need to move the DBs and related logs of Node 2 to the new storage box
I have found some information about how to deal with this (below I’m listing a KB link) but I would like to reconfirm a couple of things to make sure I’m understanding this correctly
Move the Mailbox Database Path for a Mailbox Database Copy:
https://technet.microsoft.com/en-us/library/dd979782%28v=exchg.141%29.aspx
According to the KB: “If the mailbox database being moved is replicated to one or more mailbox database copies, you must follow the procedure in this topic to move the mailbox
database path”
Would this apply to my case even when I’m moving the BDs copies and Logs on Node 2 as opposed to Node 1 where the source DBs are?
On step #3 in the procedure, you are supposed to “Remove all mailbox database copies for the database being moved. After all copies are removed, preserve the database and transaction log files from each server from which the database copy is being removed
by moving them to another location. These files are being preserved so the database copies do not require re-seeding after they have been re-added.”
Then in Step # 7, you are supposed to “Add all of the database copies that were removed in Step #3”
As far as I know, when you add a copy of a database, Exchange creates the copy DB and starts to seed the replica servers with an up to date copy of the DB and all the current transaction logs at that point…according to the instructions
above, you are supposed to re-add the DB copied we preserved...does it mean that we need to wait for the DBs seed process to finish after “adding the DB copy” and then replace the new DBs copies and logs created by the “Add database copy” function with the
DB and logs preserved in Step #3?
Thanks in advance for your feedback!

Hi there,
What the article is stating is that once you have removed the copies you can keep the existing transaction log files and database edb file to allow you not to have to do a full seed. You can do this by using the -seedingpostponed parameter in
Add-MailboxDatabaseCopy
However, and quite honestly, if your database isn't that big and your are not worried about performing a full copy of the database again to the other DAG members once you have moved your database to its preferred new location, just add the copy in the normal
way and remove the legacy files afterwards.

Exchange 2010 Mailbox Users Cannot Access 2013 Shared Mailboxes

I've a painful issue with my environment which is made up of 1 x 2010 CAS server with 1x 2010 Mailbox server and 1x 2013 CAS server with 1 x 2013 mailbox server.

If anyone could offer any help it'd be much appreciated, it's going to take several days to migrate my remaining 2010 users to 2013 which is causing a lot of use complaints.

Hi Seb,
Try the following please.
1- Remove the existing assigned mailbox permission from the mailbox.
2- Assign the permission (Add-MailboxPermission) with -AutoMapping value set to $false.
3- Launch Outlook. Then add the mailbox manually as an additional mailbox from the Account Settings. (Access to the mailbox by only following this step would also work but your user's then will have the same mailbox displayed twice hence
step 1 & 2)

Exchange 2010 Mailbox automapping issues after updated to Rollup 5 for Exchange Server 2010 SP3

Hi,
i have problem with Outlook Uses who have Full Access on other mailbox.
An authentication window pop up very time a user start Outlook.
If i remove the access everything is ok.
if i insert manual the mailbox everything is ok
The System was for 3 days ago updated to Rollup 5 for Exchange Server 2010 SP3
Before the update, was no issue.
i will appreciated any help
Thanks

Same issue here. Ever since we installed Update Rollup 5 for SP3 Exchange 2010 mailboxes that were auto mapped are not accessible. They all get the same error.
Cannot expand the folder. The set of folders cannot be opened. The attempt to log on to the Microsoft Exchange has failed.
What I have been doing is removing the users permission, then adding them back using the noautomap switch in Powershell. After doing that, the user manually adds the mailbox and all is well.
Just a note here, I suspect it may have something to do with the version of Outlook 2010. We are running an older version here. I think only SP1 with no other incremental updates. Office is up to SP2. Also, one of the users I was working with could not access
the mailbox no matter what we tried but she can walk over to another workstation and open Outlook and access the very same mailbox so that pretty much proves its software related particularly with Outlook.
I cannot reproduce the problem on a workstation (XP) with a newer version of Outlook.
This has been wearing me out and I suspected the Update Rollup all long. Now I am confident as others are having the same problem. If you find out anything on how to fix this other than the steps above, let me know.

My macbook air cannot sync with my office microsoft exchange 2010 mail server

My macbook air cannot sync with my office microsoft exchange 2010 mail server.
It used to work perfectly, and then I lost connection and was never able to establish one. I re-istalled my e-mail account several times, no success.

I am sure all of you got your email issues sorted out by now but i was having trouble settings up exchange email on my Iphone 5S, and the problem i found was to go to settings, icloud, then log into icloud with your apple id first (before setting up the exchange email). Once i logged into my icloud account on my Phone 5S, the exchange server email starting working and synching right away.
to confirm this worked, i even deleted my email account and deleted my Icloud accounts both from my iphone was able to simulated the same exact problem (exchange server would not sync with my Iphone 5S) until i logged back into my Icloud account on my 5S.
Again once i logged into Icloud, the exchange server issues went completely away.
Just wanted to post this so anyone else having the issue could see.
