No IMAP to Exchange 2003

So I ran into an issue I’ve not seen before yesterday. Couldn’t get Microsoft Outlook 2010 configured to talk via IMAP to Microsoft Exchange 2003, although the username and password was correct, it just would not connect. Turns out the answer is in this Microsoft KB article: Users Cannot Log On Using POP3 and the Error 0x80040920 Is Logged. Although about POP3 and not IMAP, the fix is the same, make both the account name and the alias in Microsoft Exchange the same.

How to: Clear Outlook Location list

Had an issue yesterday where we wanted to remove some entires from Outlooks location list.

Huh? When you book an appointment in Microsoft Outlooks calendar you can specify a location. If ACT! by Sage has a Resource that is designated as a location, when ACT! sync’s with Outlook that location list gets filled in.

So, we wanted to edit that list in Outlook. Well, you can’t.

But you can clear the list completely, which for our purpose suited us fine, it’ll get repopulated with the correct values.

Thus, without further ado, here is how you do this:

Open up Regedit and remove the value from this key:


Note that you will need to replace the version number for your version of Microsoft Office (14.0 = MSO2010, 12.0 = MSO2007).
