I am no longer able to mount newly created database on my exchange servers. It is reporting a mapiexceptioncallfailed. as per below: Any suggestions on resolving would be appreciated. thanks -------------------------------------------------------- Microsoft Exchange Error -------------------------------------------------------- Failed to mount database 'test6'. test6 Failed Error: Exchange is unable to mount the database that you specified.

So no new databases can be mounted? What if you dismount and re-mount an older database? Are you having any DC replication issues? Run DCDiag. Does the following article apply to you? http://support.microsoft.com/kb/925825/en-us Tim Harrington - Catapult Systems - http://HowDoUC.blogspot.com

I checked logs, Was trying to add a 6th database. Appears that Exchange 2003 standard is limiting me to 5 mounted database If I stop another pre-crated i was able to start the new.

Yes, you can not mount more than 5 database in Exchange STD flavour. For more than 5 DB you have to use ENT version. Anil

Hi, That's by design. Since storage group can only contains 5 databases. To create more than 5 databases, you need to create another storage group. Thanks Allen
