Hello,
We are in the process of migrating our mailboxes from 2010 to 2013. In the process of the same I encountered an issue. There is a user, suppose A, whose mailbox has been migrated to 2013 where as one of the user, suppose B, whose mailbox is still in 2010. B has the calendar access rights (owner) for A's calendar. After the migration the rights don't work anymore. B cannot make any appointments in A's calendar like she user to do before. Is there any work around for this? We need a solution for this since B's mailbox migration isn't scheduled till the next month.
Thanks in advance.
