I am looking for feedback on what the impact to the campus community would be if we stopped offering IMAP and POP3 connectivity to our Exchange 2010 e-mail system. As I understand things, for the past several years, we have allowed people to connect to our mail system using IMAP/POP. However, we don’t know if anyone has or is still getting mail this way.
There are some security issues that need to be addressed if we continue to provide support for these protocols. By turning off the ability for these protocols to be used, we can eliminate those issues easily and without cost.
So I am looking for input from those closest to the users whether or not we should stop offering IMAP/POP support. Please leave a comment to let me know what you think.
Thanks!
Only 13 unique names are currently/recently connected via IMAP (non-secure port 143). Secure IMAP is not available on the legacy mail system.
I will see if i can determine the same information for POP3. I currently see 0 people connected via POP3 in the entire Exchange organization.
Those might be Mac users using Entourage or Apple Mail. Once you migrate them to Exchange 2010 they can use Office 2011 Outlook with EWS.
