I have three Internet clients defined in Outlook. One POP3 and two IMAP
I have the same accounts defined in Outlook on three machines.
I have Outlook 2010 and 2013 on one machine.
Accounts A,B, and C receive mail on machines 1 and 2 in Outlook 2013
Accounts A,B receive mail but Account C gets no new mail on Machine 3
Machine 3 receives mail from account C in Office 2010 on Machine 3.
So machine 3 does not receive new emails with Outlook 2013 on only account C.
I have started Outlook 2013 on Machine 3 in Safe mode.
I have checked the Junk email folders and they are not receiving the email for Outlook 2013 on machine C.
Since account C works fine in Outlook 2013 on machines 1 and 2, something is blocking in on machine 3.
