Hi Everyone
We have exchange server 2010 SP1 deployed in our environment.
We have 3 mailbox server deployed in DAG. We have around 600 mailboxes.
For the last few days our Offline Address Book (OAB) is not getting updated.
The error in the EventViewer is :
OABGen detected that the file '" "" is corrupted or missing. This indicates data tampering or disk problems. Restore files in this folder from the recent backup or clean up folder content and force a full OAB generation.
As backup is unavailable, we need to proceed with full OAB generation.
Kindly let me know what are the risks/things to be considered for full OAB generation and how much time will it take at the user end for the updated Address List to be available.
We have 600 mailbox users and they connect through WIFI
