Recently, we have upgraded Zimbra from ZCS 8.7.11 to 8.8.5. But we found one issue when using Microsoft Outlook 2007 to check incoming email. We set to use POP3S, port number is 995 (SSL).
When we check incoming emails, it pops up the error as below:-
Task 'firstname.lastname@example.org - Receiving' reported error (0x800CCC1A) : 'Your server does not support the connection encryption type you have specified. Try changing the encryption method. Contact your mail server administrator or Internet service provider (ISP) for additional assistance.'
BTW, if using Outlook 2010, no this issue. So we don't know whether it is Outlook 2007 bug or not.
Appreciate someone can fix this issue.
Thank you in advance.
Discuss your pilot or production implementation with other Zimbra admins or our engineers.
