Exchange Server 2003 Mailbox Store Couldn’t Startup Automatically, there is mayn reason of it. I had a Case related of it.
If you got the following Errors while Exchange 2003 Mounting. You can apply theese solution steps
The store could not be mounted because Active Directory information was not replicated yet. You can eighter;
– Press Cancel and Mount the store later from is context menu or,
– Press Retry to let the Exchange System Manager keep trying to mount the store for you.
Event ID : 9175 => MSExchangeSA / The MAPI Provider failed.
Event ID : 2115 => MSExchangeDSAccess
Finally, we got the solution of it.
It was the Mailbox Security Properties.
For the solution;
Expand First Storage Group / Mailbox Store / Properties / Security / Advantec
Check ” allow inheritable permissions from parent to propagate to this object and all child objects”
Then restart the Server.
