   <description>Email Syncing stops working with imap error.

The following happens:

- The active Sync client tries to delete messages which are already deleted on the imap server
  from this point on, no new messages will be shown on the active sync client.

Reason of this situation:

Often there is an UMTS connection problem (e.g. the UMTS network of some providers in germany is very crowded). The active sync client has no connection because network is switched off ...

Then during an access with another imap client (e.g. thunderbird) inbox is cleaned up.

Now after reconnetion the active sync client tries to remove messages which are already removed, and refuses to sync now.

The following sync log could be observed during this situation:
