Thinking about it some more, the only thing I can think of is that the Outlook assumes that the separator is a '/', or some other character that is NOT a '.', so creates the folder locally before it receives the acknowledgement from the ActiveSync server (there were other, similar issues with OL where it didn't care what the server responded). My guess is that the folder IS being created, but it's being created as a subfolder. I.e., 'test.folder' is being created as: Test \| \|--folder If that's the cast there really isn't anything we can do about that since the client is ignoring the server response.

I'm afraid that I'm not able to provide debug data. I can only give you some more information about the IMAP server. It's a Courier-IMAP using Maildir - the dot is the directory separator char (I suppose, the dot is a quasi-standard). Unfortunately the Courierlogs also gives no hint about the reason - maybe the folder creation fails before it goes to the imap server? You are going to have to find out where and why this fails. I can't reproduce and without more information there isn't much we can do to help.

(Related bug https://bugs.horde.org/ticket/6076 ) When creating new folders over an Active Sync client (tested with Outlook 2013 and 2016) there is no input validation for dots in the folder name. There is no reason why a '.' should be disallowed. IF this is the configured separator on your IMAP server, it would create a sub-folder structure. If it is NOT the separator, then there is no reason why it should fail. Please enable IMAP debugging (see imp/config/backends.php) and provide the IMAP log of when this fails. Also check other horde/webserver error logs for any relevant entries. Instead the folder isn't created on server but since there was no error at the client the folder exists local. According to our users this results in strange issues and breaks the sync completely.
