[Users] MS exchange 2010 ,IMAP authentication

Wed Jan 23 10:25:37 CET 2013

Hi 
I don't if my previous posting got through, I haven't seen it.
Hence asking if the list was still active.
I had problems with slow downloads last year ans switched to TBird, as it didn't exhibit the
speed problem. Since then my ISP has upped the the connection to 30Mb.
From last weekend TBird showed authentication errors, continually requesting a new password
with IMAPs, changing to non secure IMAP helped a bit.
After spending all with the support team on my mail provider, I switched back to CM as its logging
is far superior.
I found that  the mail host had changed everything to STARTTLS, but also the use of LOGIN had
changed to GSSAPI.
 I'm still getting authentication problems when moving up or down the folder tree, sometimes it
 succeeds , others not.
The log file shows:-

From this it looks as if the initial exchange with TLS and GSSAPI is OK, then instead of staying
with GSSAPI , CM uses LOGIN.
I have the authentication method set to automatic , It seemed to cause less errors.
There is also the BADCHARSET (US-ASCII) , does anyone know what is need here, I've tried UTF-8
which it doesn't like.
I'm wondering if there was an update issued by MS, as all was working well until Saturday.
My Gmail account works fine, apart from losing a large proportion of mail from mailing lists,
hence the use of a 3rd party mail provider.
There's very little on the wiki etc on exchange2010 with CM, its mainly exchange2007.

Any help with this really appreciated

CM 3.9.0 FED FC17

TIA
