Dear All, In my Ex 2010 SP1 (Server 2008 R2 Ent SP1) I have three database files for three user groups in three different offices. Today a user tries to import an old 4GB PSt file (with possible corruptions etc in it). Half way through the import fails. After this the relevant database with this user's account belonging to dismounts in the EMC, therefore all those users whose accounts are in this database have gone offline. I take two backups daily one at 13:00 and one 19:00 using Windows 2008 backup. The corruption happened shortly after the 13:00 backup, so I can restore this backup and restore the database file in question BUT I only backup the drive hosting the database files (The F drive) and NOT the C drive. Can I go ahead and restore the file, someone told me that I need the transaction logs which are normally on the C drive. Please advise as I need to resolve this before the morning when my suers come to the office. Many thanks in advance, BinaBina Hejazi

Have you tried to remount the store?

Hi Andy, Thanks for your note. the Store service is running and the other two databased are mounted and up & running. why would I want to stop/restart the Store? (if I understood you correctly) BinaBina Hejazi

Did the store actually dismount or did the users just lose connectivity? Reason I ask is that there is an issue out there with Legacy data that Exchange 2010 will puke on during the import. Most of these have been resolved by having SP1 and all the latest roll-ups installed, however we have heard of a few situations where this still occurs and when it does then the CAS service is actually halting or restarting, but I haven't heard of a store dismountingTroy Werelius www.Lucid8.com Search, Recover, & Extract Mailboxes, Folders, & Email Items from Offline EDB's and Live Exchange Servers with Lucid8's DigiScope

Right now one store is dismounted yes? What happens if you try to mount it?

Andy, The Store never dismounted. I have RU5 installed. The thing is that I have 3 Databases. Only one is dismounted that I cannot Mount. do you think stopping/restarting the Store might resolve this. I just fear that once I stop the Store it may not start again and the other two running databased also go down. at the moment all messages destined for the users on the dismounted database are in the queue. none of my Exchange services are stopped. any suggestion? Thanks - BinaBina Hejazi

Ok, I think is some confusion of terms here. You say the store never dismounted, then you say only one is dismounted. When you try to mount the one store that is dismounted, what happens? If it fails, what are the exact and full event log errors?

nothing, it tries and fails and shows dismounted again! I have done it several times!Bina Hejazi

And nothing in the event logs? That would be very unusual.

Andy, by Store Itake it U mean the Store service, I see what you mean now. The event log after it fails to mount is: Exchange Search Indexer failed to enable the Mailbox Database BH-Users (GUID = 3b25451f-19db-4ce1-8cb4-6a0e9cb62565) after 1 tries. The last failure was: MapiExceptionMdbOffline: Unable to get CI watermark (hr=0x80004005, ec=1142) Diagnostic context: Lid: 1494 ---- Remote Context Beg ---- Lid: 44215 Lid: 60049 StoreEc: 0x8004010F Lid: 49469 Lid: 65341 StoreEc: 0x8004010F Lid: 56125 Lid: 47933 StoreEc: 0x8004010F Lid: 32829 Lid: 49213 StoreEc: 0x8004010F Lid: 48573 Lid: 64957 StoreEc: 0x8004010F Lid: 9518 StoreEc: 0x476 Lid: 1750 ---- Remote Context End ---- Lid: 8434 StoreEc: 0x476 Bina Hejazi

Andy, for further info, I ran the eseutil.exe on the database (dismounted) and it came back with "Integrity check successful" Rgds, BinaBina Hejazi

and you have enough disk space? My first thought if you cant mount the store is to bounce the server and try again, but I know you are hesitant to try that.
