Hello - we've started our E2K7 to E2K13 migration. Noticed E2K7 mbx running Outlook 2007 SP3 cannot view any E2K13 mbx calendars, get error that server is not available. If the same E2K7 mbx user opens mbx with Outlook 2013, the user can view the E2K13 mbx calendar.
Saw something about this error being related to E2K13 Address book service ... per other post, having OAB issue, so may be related. Any suggestions, or should this work out of the box? Autodiscovery is setup and working.
Thanks.
