Z-push 2.4.4 - Autodiscover not working.

Hello,
I got a z-push 2.4.4 with zimbra backend, and everithing works when manually setup.
When I use autodiscover nothing works at all.

I tried a check with microsoft remote connectivity analyzer.

  • Microsoft Exchange ActiveSync Connectivity :
    The conectivity test is successful but when I tries to setup the account on an android outlook apps, it’s not recognised as an activeSync account an return an Imap configuration.
    With another apps like gmail selecting “exchange account” the xml isn’t send and I got to manualy set the server.

  • Microsoft Office Outlook Connectivity Tests :
    I got the following :

03/08/2018 15:50:41 [11270] [FATAL] [#unknown] Exception: (FatalException) - Request for a responseschema that is not supported (only mobilesync is supported): http://schemas.microsoft.com/exchange/autodiscover/outlook/responseschema/2006a
03/08/2018 15:50:41 [11270] [ERROR] [#unknown] Unable to complete autodiscover because of ZPushException. Error: Request for a responseschema that is not supported (only mobilesync is supported): http://schemas.microsoft.com/exchange/autodiscover/outlook/responseschema/2006a

I would assume that your Outlook client is looking for an Outlook Web Access type connection rather than an ActiveSync connection. That type of connection is not supported by Z-Push
