Hi,
I've done some debugging and attached are (parts) of 2 strace files.
correct.txt. This is when I click on a folder in Outlook and everything is
OK (no headers are retrieved etc.)
wrong.txt. This is when I click on a folder in Outlook and it starts
retrieving all the headers again.
Im not sure what to look for in these files.
Cheers,
Jan

I am a bit hesitative for debugging on production I will try and see if can
set up some sort of test env. to debug.

Please give us some more information. Output of `dovecot -n` would be a good
start. Also check the logs for dovecot reporting problems (and/or switch on
debug logging).
