Please describe the problem:
When accessing my mailbox both with an Evolution/MAPI and a native Outlook client, all operations made through Outlook are not detected by Evolution. For example, if a delete a mail with Outlook, Evolution will still show it in the summary list. Evolution will though fail to display the mail summary (telling that it cannot retrieve the message from the server). This behavior remains even if I restart Evo (with a --force-shutdown).

Steps to reproduce:
1. Launch Evo and retrieve mail summaries
2. Shutdown Evo
3. Delete one of messages with Outlook
4. Launch Evo: the deleted message still appears in the list


Actual results:
The deleted message still appears in the summary list although the message has been deleted from the server.

Expected results:
The message summary should have been removed from the list.

Does this happen every time?
Yes.

Other information:
This behavior is not linked to Outlook, the use of the web client leads to the same problem.
