The error messages are:

1) "Connection to XXX (email address) server timed out..." 2) "Current operation on inbox not succeed..." 3) "Server XXX (email address) has disconnected..."

For your information, I'm using 6 email accounts, all setup with IMAP, from outlook.com and gmail.com, my OS is Windows 7 Pro, and the errors never happened previously. I tried searching everywhere possible but found no solution.

Thanks in advance to those who may help to solve the problems.

Does this happen for all the accounts or just the outlook.com ones? You might be able to tell from Tools/Activity Manager.

Just the Outlook accounts.

There are some new settings for outlook.com accounts that fix the problem with timeouts.

Problems seem solved after I changed the server settings of the Outlook accounts to: Incoming server: Outlook.Office365.com, Outgoing server: SMTP.Office365.com. Thank you!
