mailbox move request having no progress also no failure

hi there,

I have a strange problem, we are moving the whole list of mailbox's from one DB to another DB.

its a Exchange 2010 SP3 infra, where the whole list of mailbox's are sucessfully moved the new DB, except one mailbox.

that particular mailbox is not having any progress beyond 10%, total size of the mailbox is 4GB and the number of folders/subfolders in that mailbox is 4000+

we have cancelled the move request and tried multiple times but it never crossed 10% and also it throws no error even after keeping it ON for 48 hours. anyone having idea how shall we kick start ot force the mailbox move request?

Hi,

Take a log of the move activity as follows. Do a move through PowerShell. Before starting the actual Move, include the following line of cmdlet. This will record all the logs in to a text file as indicated.

start-transcript -path c:\temp\transcript.txt
Evaluate the log file after a certain amount of time and see if you can see something weird. To stop the transcript, run Stop-Transcript

I tried below command but the move request is stuck , last message that shows in the log is "initializing the folder hierarchy, 4006 folders total"

New-MoveRequest -Identity
tony.smith@contoso.com' -TargetDatabase "Contoso" -BadItemLimit 100 AcceptLargeDataLoss

Hi,

Looks like the folder hierarchy is somewhat not able to understand by Exchange server. Can be a bug in Exchange server too.

Can you check, if Rollup 10 is installed on Exchange server ? Rollup 10 is addressing a kind of issue like this as mentioned  here:

Rollup 10 of SP3 can be found here:

Hi Manu, thanks for your input, as we dont see any error I dont thing this article is related to my issue.

because this article is related to the following error : MapiExceptionNoAccess: Unable to query table rows.

do you see any workaround to this issue atleast? I dont want to export and import the mailbox :(

Hi,

Please run the following commanf to check your move request:
Get-MoveRequest -Identity User1@domain.com | fl
Get-MoveRequestStatistics -Identity User1@domain.com | FL

Since there is no error or warning during the mailbox move, please complete or Resume a Move Request to have a try. If it fails, please clear all completed request and create a new move request for this specific user to move it.

If all fails, please consider to export and import this particular mailbox by PST file.

yes we tried these commands already and tried to move the mailbox multiple times, but no luck so far, so finally we had to propose an export-import option, but customer is bit unhappy with that as the export import has outage to that particular mailbox during cutover, my main problem is unable to convince the customer as we dont know why the move request is not sucessfull.

I think this is the best option that I feel like to go with: 

1. Export the mailbox as PST file.

2. Disable the mailbox, so the AD opject remains same and only the mailbox is removed.

3. Recreate the mailbox on the same AD object, so an embty mailbox is created.

4. perform an Import request onto the above created mailbox.

Do you think, anything else I need to take care apart from the above points?
