Just a quick question to see if anyone can give me any direction in or solve the the following problem:

Within the office there are a minority who use Outlook client using IMAP: Dovecot and the rest use Thunderbird on Linux also using IMAP: Dovecot via the same mail server. The people who are using Outlook 2010 are repeated (almost daily) reporting outages of emailing services for hours at a time forcing them to sign in and out etc but the people using Thunderbird do not have any issues what so ever which I assume will rule out an issue with the old mail server we are currently using.

Any help in the matter would be hugely appreciated and of course if I can provide any further information to articulate understanding of the issue then please just ask.

@DaveRook yeah that is absolutely the case. – BarmyArmy Nov 1 '13 at 9:58
Thanks for the heads up – BarmyArmy Nov 1 '13 at 10:11
I suggest first seeing if the same issue persists if Outlook is run in safemode to rule out any plugins or conflicts. I would also check to make sure that it is using the same ports/security etc – Dave Nov 1 '13 at 10:22
Thanks @DaveRook I heard there is some sort of Outlook Diagnostic Tool that may be of help. Would you recommend that and how would I access it? – BarmyArmy Nov 1 '13 at 10:30
I have looked online. The material suggest that the tool resided in Programs > Microsoft > Microsoft Office Tools but I only have a folder named Microsoft Office 2010 Tools which does not contain the Microsoft Office Diagnostics program. Thanks I appreciate it. – BarmyArmy Nov 1 '13 at 10:37
