Hello,
We have experienced a very strange issue on our SBS2011 Standard server. We run Exchange 2010 which has been working perfectly fine for the last 2 years since the initial install until 2 days ago when at 2pm outlook lost connectivity to Exchange. When logged
into the Exchange MC I noticed that the mailbox database was dismounted. when trying to mount the database I receive a Mapi Exception Network Error with codes (hr=0x80040115, ec=-2147221227). I checked the AdServerSettings and it points to the domain as it
should.
I attempted to mount within the exchange shell but it fails as the MSExchangeIS service is not started and when I checked this service I noticed that it starts and stops every few seconds, the only time this stops is if the service is disabled.
There are several mapi issues raised under this code on several forums but not one of the solution/fixes sorts out this problem. Any ideas out there?
