We just migrated from Exchange 2003 to Exchange 2010 as an intermediate step to going to Exchange 2013. Everything is working through OWA, so all the data has been transferred. We have users that can access Outlook 2010 through a Citrix server, and through their local workstations. Outlook 2010 is working fine through Citrix as well, but on all users if they access Outlook 2010 on their laptop they get an error when trying to do Out of Office messages, and they can't see free/busy time for other users when adding them to meeting invites.
I already have a post about the issues, but since we are moving to 2013, could the migration fix these issues, or do we need to resolve them first? The data is clearly there, so I don't think that's the problem.
Thanks!
