Hi, I'm currently investigating a problem I have in my exchange 2013 server.
We migrated from 2010 to 2013, and now I'm decommissioning 2010 mailbox servers.
I then dismounted my old database, and now I've this event prompting, seems now exchange is unable to deliver voicemail notifications.
What's turning me crazy, it's the server trying to open mailbox "Microsoft system attendant". now I'm scared about removing this DB, containing this "mailbox" that i can't find anywhere (just with ASDI Edit in the DC) so I can't migrate
it or nothing.
(I'm aware that this service is not used anymore, that's why I don't understand this issue).
this is the EVENT:
The Microsoft Exchange Unified Messaging service on the Mailbox server encountered an error while trying to process the message with header file "C:\Program Files\Microsoft\Exchange Server\V15\UnifiedMessaging\voicemail\092540a2-50b1-4b91-b408-c3595a677e25.txt".Error details: "Microsoft.Exchange.UM.UMCore.MailboxUnavailableException: "MessageType:CDR Database:CN=OLDDATABASE,CN=Databases,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=COMPANYNAME,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=COMPANY,DC=com
