Yep - db is i trouble
If the user has Cached Mode enabled then you may be able to extract email by unpluggnig network cable from computer and exporting with outlook disconnected......
Go the restore, and take more regular backups :)
1. Dismount databases and stop info store server and make copy of MDBDATA folder first - you never know if we will beed to come back to this. Then restart info store service.
2. follow instructions in article I posted. Dont forget the missing step
After you have dismounted the stores to prepare for the backup, goto the properties of each store, database tab, and tick the box for "This database can be over written by a restore"
3. If it does not mount after restore, don't stress it is probably a mismatch in the log files. We can easily remove the old log files to get it going.
