Created attachment 8749093 [details] thunderbird-update-mailabruf.png User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0 Build ID: 20160407164938 Steps to reproduce: Did the (automatic) upgrade from Thunderbird 38 to 45. Start Thunderbird Actual results: No connection to my set IMAP servers is opened on startup. Although I set the ""Check for new mail at startup" switch on all servers. I need to explicitly select "Check all servers" from the "buttons-menu". Expected results: The switch should work as before again.
Have you tried the safe mode which I proposed in bug 1270408? This is likely a extension issue.
Tried reproducing the bug with add-on Quicktext enabled without the safe mode. I have just one IMAP server but two email addresses. Both of them are checked for new messages on start-up.
Thanks for quick response, and sorry for my late reply (caused by holidays here). Finally it was about Mnenhy, as posted in 1270408 - so I close this ticket.
