Hi There
I'm troubleshooting an issue during a exchange 2010 to exchange 2013 migration where the OOF is not working for users homed on the exchange 2010 mailbox servers. This applies to users using outlook 2010 and outlook 2013 .OWA works perfectly and you can also enable OOF via exchange powershell.
Users homed on the exchange 2013 servers does not have any issues.
The exchange 2010 servers is on SP3 rollup 4 and the 2013 servers on SP1 only without any rollups installed.
So my question will be - have anyone experienced this issue during migration and will patching the exchange 2010 servers to rollup 5 or 6 and the exchange 2013 to sp1 rollup 5 fix the OOF issue then? If requested the client to patch to these levels, but in the meantime I'm checking if anyone else had similar issues.
Any pointers will be welcome.
