Hello ,


I have an Exchange 2007 and i have a problem exporting a mapi user mailbox to pst. It seems that it has a lot of corrupted items and the powershell script stops when it finds such items. I try to use the -baditemlimit but it seems that the corruption is huge and only 20G of the 60G of the mailbox can be exported. Is there something i can do to fix this mailbox ?

Thanks

Hi

Try to hook Outlook to this account and have it download all mail, if this succeeds it is easier to troubleshoot locally.

Moving the mailbox to another database will often clear corruption.  However in Exchange terms, a "corrupt" item can also be an item that is too large for the size restrictions.

I also try to setup outlook and sync mailbox but it stop syncing when the mailbox reach about 20G of data. The same happens when i try it with powershell .

Any other ideas ? Sembee do you thing that the mailbox move will solve my problem ?

Does Powershell have you tied up in knots?

Just noticed that the mailbox is 60gb. That is your problem with doing an export.

PST files have a limit of 20gb. That includes OST files as well as they use the same underlying format, so if Outlook is in cached mode then it is going to stop at 20gb.

Therefore you will have to do multiple passes of the mailbox with the export tool, probably using filters to try and restrict the content being exported.

I remember that 20GB is outlook 2003 and outlook 2007 limit . Im using outlook 2010 and 2013 but the sync of the mailbox stops at 20G .

The limit hasn't changed.
It is still 20gb.

Please create a new mailbox database on the same storage group and transfer the mailbox to it. In the Move options, select the "Skip the corrupted messages" and set the value.
