The problem started after I upgraded Outlook 2010 to Outlook 2013. I had moved from an on-premise Exchange server to O365 several months ago and everything had stabilized. We are a hybrid Exchange environment with the on-premise Exchange and the O365 working concurrently.
After upgrading the Outlook desktop to 2013, the following statement pops up whenever I try to send a tracked email.
I checked my email information as a CRM User and it hasn't changed. Perhaps since the address is the same in O365 and on-premise Exchange something is handled differently by Outlook 2013?
How / What do I need to change to be able to send email without this problem?
Thanks,
Gary
