I am running SOGo 3.0.2 with OpenChange 2.3. Everything runs very well for smaller mailboxes but I can't get an initial sync with Outlook using MAPI for mailboxes that are 2+gb and/or with lots of folders. In the Samba logs I see tons of lines like this which appear to loop over and over:

  mapiproxy/libmapistore/mapistore_backend.c:345(mapistore_backend_create_context): namespace is sogo:// and backend_uri is ''...

and doing a tcpdump on the IMAP port it seems to be looping around doing LIST on all the folders over and over, but not doing any actual message fetching.

In Outlook I see an 'Updating Folder...' status that lasts for ever. The OST file is only 16mb which must mean it didn't transfer any actual mail.

I don't have this issue with smaller mailboxes.

I've grepped the Samba logs ( debug level 8 ) for ERROR but nothing comes up.

Has anyone else encountered this issue ?
