Hi,
Installed Unite and configured same IMAP account as in Outlook.
From that point in time, had Outlook error saying that a "connection to the IMAP server can't be establihsed and that account is now offline".
Removed the account on Unite, and Outlook is fine again.
Did anyone had the same problem ?

Surfing a bit, I found a couple of thread where the point of having several IMAP connection on same host from a single computer creates that kind of issue... does that mean that there's no real solution ?

One that I could see would be that Unite checks if Outlook is open, in which case it stops polling the IMAP account. And that make quite some sense as if you're reading your emails on Outlook, there's no need to push them at same time... Any other proposal ?

actually I've asked my ISP to increase the number of concurrent IMAP connections (from 4 to 20) and the problem is solved...
