From time to time there are problems with the out-of-office assistant. I recently had an interesting problem with the out-of-office messages, and I don't want to withhold the solution.
The out-of-office assistant was set up correctly by the user and the mail tips were also visible in Outlook for internal users. However, no e-mail was sent about the absence, neither to internal nor to external addresses
As already mentioned, the Out of Office Assistant was configured correctly and everything looked normal in the Exchange Shell:
Sending out-of-office messages to external domains was also permitted:
Nevertheless, as already mentioned, no message was sent to internal or external users. The message tracking showed that no message was rejected or discarded. No mail was simply created.
Using MFCMapi, I was finally able to solve the problem (Download MFCMapi):
First deactivate the Out of Office Assistant. Then run MFCMapi and connect to the corresponding mailbox:
After logging in, double-click on the mailbox:
Unter dem Ordner „IPM_SUBTREE“ einen Rechtsklich auf „Posteingang“ ausführen und „Open associated contents table“ wählen
In meinen Fall gab es zig Einträge mit der MessageClass „IPM.Note.Rules.OofTemplate.Microsoft“. Diese Einträge habe ich alle gelöscht.
Once all entries have been deleted, the out-of-office assistant can be reactivated. The out-of-office messages should now work again:
The following classes can also be problematic:
- Message class: IPM.Rule.Message
0x65EB001E == Microsoft Exchange OOF Assistant
0x65EC001E == Microsoft.Exchange.OOF.InternalSenders.Global - Message class: IPM.Note.Rules.OofTemplate.Microsoft
- Message class:IPM.Rule.Message
0x65EB001E == MSFT:TDX OOF Rules - Message class:IPM.Rule.Message
0x65EB001E == Microsoft Exchange OOF Assistant
0x65EC001E == Microsoft.Exchange.OOF. AllExternalSenders.Global - Message class: IPM.Note.Rules.ExternalOOFTemplate.Microsoft
- Message class: IPM.ExtendedRule.Message
0x65EB001E == Microsoft Exchange OOF Assistant
0x65EC001E == Microsoft.Exchange.OOF.KnownExternalSenders.Global
As already mentioned, in my case the entries were duplicated and triplicated. It was enough for me to delete these messages: IPM.Note.Rules.OofTemplate.Microsoft
