Hi guys, after deploying SP1 for Exchange 2010 last friday i get unfortunately 2 error messages recorded in event logs: event id 3154 Active Manager failed to mount database Mailbox Database 2128318158 on server host.domain.local. Error: An Active Manager operation failed with a transient error. Please retry the operation. Error: Database action failed with transient error.

But both database are available and mounted. How to get rid of these messages? And i get these 3154-event error messages only by rebooting the whole server not if i restart restart exchange (MSExchangeADTopology). thanks alot! uxmax

just an update: i get the same error for every new blank database iam going to create. not sure if this error can be ignored or not in doubt go back to the snapshot before the sp1 install

I want to migrate/transition our 2003 Exchange Server Mailboxes to 2010. here is another thread about the problem: http://social.technet.microsoft.com/Forums/sr-Latn-CS/exchange2010/thread/ee1895f7-cec6-4a37-be8a-4bdd621e8bc4 could not mount database error logged but all databases have been mounted and are accessible. iam thinking about going back to the 2010-without-sp1 snapshot state and postpone SP1 Installalation until i moved every mailbox and deleted the 2003 Server.

looks like i fixed the problem myself. i set all services from "automatic" to "automatic delayed start" and all errors are history and gone after a reboot. thanks, uxmax
