issues after migration to exchange 2010
 

Hey folks,

Been a looooong time since I've posted here, mainly because our BES has been running pretty well, but I'm having some issues now.

At the beginning of the year we migrated from 4.1.x to 5.0. That was a bit of a painful upgrade, but I got it sorted out well enough. Now we have just upgraded our Exchange server to Exchange 2010, and I'm having a whole bunch of issues. This isn't happening to every account, but for the users who are affected, I am having connectivity issues. Setting up a new user, and the BlackBerry will not activate, the email get stuck in their inbox. I have a few users who's devices have stopped syncing. Sometimes rebooting the BES server fixes the problem for a few hours, sometimes it doesn't.

I looked through the log files, and I am seeing MAPI errors on the affected users, but I have confirmed that the MAPI file is identical on both the Exchange server and the BES server. I even grabbed the most recent version from Microsoft and put it on just to be sure.

Here is the specific error for one user:


At this point I'm almost at a total loss as to what the issue could be.

I'm running BESX 5.0.1 MR1 on Server 2003 R2, and the Exchange server is Exchange 2010 on Server 2008 R2. I'm going to be upgrading to MR2 after hours tonight, but I don't think any of the bugfixes listed in the release notes will help me out much.

Have you ran the commands to remove the limit of active connections???

Increase the maximum number of connections to the Address Book service in Microsoft Exchange 2010

I hadn't done this. I changed it and will see what happens.

Well, I made that change, waited an hour, even restarted the BES, and I still have 5 users who will not sync at all. Everyone else is working fine.

OK try this...

If you followed the official BES 5.0.1 install guide you would have issued the following two commands:

New-ThrottlingPolicy BESPolicy

Set-Mailbox "BESAdmin" -ThrottlingPolicy BESPolicy

These two commands would have created a new policy and added BESadmin with all the default settings (RCAMaxConcurrency = 20) which will cause the "OpenMsgStore failed (8004011d)" error to occur once multiple users are added to the BES.

To correct this error please enter the commands below into the Exchange Management Shell:

1. Change the RCAMaxConcurrency setting to unlimited (default is 20) using the following command:

Get-ThrottlingPolicy | where {$_.IsDefault -eq $true} | Set-ThrottlingPolicy -RCAMaxConcurrency $null

2. Display a list of your Throttling Policies using the following command:

Get-ThrottlingPolicy

3. From the "Get-ThrottlingPolicy" output locate and copy the "DefaultThrottlingPolicy" name.

Example: "DefaultThrottlingPolicy_a1f84187-7a42-4ece-9276-06c704be21e7"

4. Now enter the command below but paste in your DefaultThrottlingPolicy name.

Set-Mailbox "BESAdmin" -ThrottlingPolicy <Default Policy Name>

Example: Set-Mailbox "BESAdmin" DefaultThrottlingPolicy_a1f84187-7a42-4ece-9276-06c704

5. Now we need to remove the BESPolicy that isn't required by issuing the command below:

Remove-ThrottlingPolicy BESPolicy

I will give this a try and report back. I had found a guide, and tried changing the RCAMaxConcurrency setting to unlimited, but not where I had to change the throttling policy BESAdmin was on.

They decided to upgrade exhchange servers while i was on holidays, and they did follow the guide for exchange 2010, but because I wasn't the one who did it it's hard to know exactly what they did, which makes this all that much harder to nail down =/

wunderbar,

I had this EXACT issue. I set all of the throttling policies to no avail. However, after installing Exchange 2010 Rollup 2 my issue was finally resolved.

I hope this helps. If you are like me, you were ready to kick kittens over this.

Thanks, Knotty!

Welcome 8-)

Ok, bigwilloc's suggestion did not work, even after a reboot of the BES server. we are already on update rollup 2 for exchange, so that's a no go either.

I'm almost at the point where I just need to go through the entire checklist again on the exchange server. I'm completely dumbfounded as to why this is affecting 5 out of 40 users, and was working just fine 2 days before.

Well, I went through most of the checklist, and still nothing. I opened a ticket with RIM (we only have email support) 2 days ago, and still haven't even received a reply.

This is getting really frustrating.

You can get a free support call, look at my signature

Any Luck?
 

I'm having the same problem.

Have you come up with a resolution?

No resolution so far, I'm still working with RIM T-support. I actually have a new issue as well, some users, unrelated to the issue with no users working at all, are having calendar sync issues, as in, it's not working.

Gotta say not impressed with RIM right now. This is not a smooth transition.

Hi Wunderbar,

Just to add to your proof to Rim, I too have the exact same problem, i have about 24 people in and the remainder including myself, stuck not being able do anything, if you find anything out please let me out of the hell i am in :)

Yea, I will be calling RIM today. The end of the line for email support was basically a "yea, we're not sure, you should probably call us." So as soon as I'm at my actual office instead of one of the satellites today, I'll be calling later on and will keep everyone updated as to what RIM says.

Ok folks, another symptom, not sure if it's related to the same issue or not. This appears to be affecting all BlackBerry users. When a meeting request is sent, what the user gets on their blackberry appears to be just an email, not a meeting request, with no way to accept/deny it. If i accept a request in outlook, it goes into my outlook calendar, but does not get pushed to the BlackBerry. Calendar entries created on BlackBerry do not go to outlook.

I know that the CDO is good, as I have re-installed the latest version within the last week as part of trying to fix the other issues we are having

ok, I just went through the log files and it's saying my CDO isn't registered, for some reason, so I think that's an easy fix.

I've also found something interesting in the log files, maybe someone can help me with. I found a line that points to our old exchange server, the one that was on 2007. When we moved to 2010 we also moved to new hardware, so that was part of our transition. The specific line in the log is:

[30000] (04/13 07:42:17.131):{0x36C} [ENV] Server DN: /o=Diversity Technologies Corporation/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Configuration/cn=Servers/cn=SEEXCHANGE

That's the only mention of the old server in the file, everything else refrences our new exchange server.

Could that have anything to do with the issues we are having, can anyone else having this same issue look in their logs and see if there are any references to old exchange servers?

If CDO is not registered it can do some weird things with calendar.
