Trouble With Exchange Backup

[50bc0f35-82b6-4d39-b772-5a36b28ef2ae]

Hi,

 

Exchange 2010 on a 2008R2 server, Retrospect 7.7 on another 2008R2 server :

 

I've got some mailboxes, not all that won't backup :

 

T-749: TMailboxFind::Init: GetContentsTable failed on folder 'Administrateur\System'., winerr -2147467259, error -3420

 

while some others backup fine.

 

After a long, long, digging into the problem, I noticed that the only diffference between "good" mailboxes and "bad'" ones is the localisation of folders :

 

A good mailbox :

 

[PS] C:\Windows\system32>Get-MailboxFolderStatistics gooduser

RunspaceId : 08b8ba1e-7c67-4e73-8696-e90a6c5ad785

Date : 02/01/2011 23:19:53

Name : Top of Information Store

FolderPath : /Top of Information Store

FolderId : LgAAAACDLaALz+ZHTbWNPMhreuVCAQBoVXLrDVQbRLwgtyKaMd9aAAAAJ1XnAAAB

FolderType : Root

ItemsInFolder : 0

DeletedItemsInFolder : 0

FolderSize : 0 B (0 bytes)

ItemsInFolderAndSubfolders : 196

[...snip...]

 

A bad mailbox :

 

[PS] C:\Windows\system32>Get-MailboxFolderStatistics administrateur

RunspaceId : 08b8ba1e-7c67-4e73-8696-e90a6c5ad785

Date : 14/12/2010 10:25:11

Name : Partie supérieure de la banque d'informations

FolderPath : /Partie supérieure de la banque d'informations

FolderId : LgAAAAAUfPCJpaPDQ5aIjH2VIPs4AQC24qGP/9FnRqZ5F8dfGqFtAAAAh95kAAAB

FolderType : Root

ItemsInFolder : 0

DeletedItemsInFolder : 0

FolderSize : 0 B (0 bytes)

ItemsInFolderAndSubfolders : 13

DeletedItemsInFolderAndSubfolders : 0

FolderAndSubfolderSize : 15.38 KB (15,746 bytes)

 

You can see that Folder Path/Names are translated in French on the problematic mailboxes. I checked randomly a dozen, and this is consistent : French names -> can't backup, US names -> backup ok

 

I'm not sure this is really a Retrospect problem, perhaps, there is a way in Exchange Management Shell to rename the folders inside mailboxes, but I didn't find one.

 

[Edit] :

the CmdLet Set-MailboxRegionalConfiguration does partially the job : using en-us locale, with -LocalizeDefaultFolderName=$true renames the folders, but *not* the top level ( /Top of Information Store vs. /Partie supérieure de la banque d'informations), so the error -3420 (winerror 0x80004005) is still here...

 

Since the Exchange server is perfectly functionnal, from users point of view, maybe it is eventually a Retrospect problem...

 

Thanks,
