This has happened to me a couple of times; I reboot my server and attempt to connect Thunderbird (from my Ubuntu desktop) back to my Exchange mail server (on an SBS 2003 machine) and I get this message which ends in “error code -12263”.
Oh, what? You don’t know what 12263 is? Beats the fuck outta me.
A Google search yielded several problems which barely applied to my situation (most of them dealt with this error in relation to secure Web sites using https) and I found some information about a certificate problem (which actually dealt with Thunderbird). None of the offered solutions did me any good.
However, this was all pretty good information for me. I hopped over to my server and attempted to restart IMAP4:
- Right-click on My Computer
- Choose Manage from the context menu which appears
- Find Services and Applications on the right
- Click the + to expand Services and Applications
- Locate Services below that and click on it
- Right-click on Microsoft Exchange IMAP4
- Choose Restart from that context menu
That failed for me too. But IMAP is dependent upon IIS Admin Service (Internet Information Services):
- Start –> Programs –> Administrative Tools –> Server Management
- Expand Advanced Management
- Expand Internet Information Services
- Right-click on [YourServerName] (local computer)
- Choose All Tasks –> Restart IIS… from the context menu
So, looks like it was useful information that other folks were experiencing problems with secure sites.
I then restarted IMAP4 again just to confirm it would restart. After that I was able to connect to my various mail boxes from Thunderbird without issue.
