      The first time I open Outlook after creating a new profile I can see the Device ID in my Apache logs:

      x.x.x.x - xxxxx@xxxxxxxxxx [30/Dec/2021:01:23:43 +0000] "POST /Microsoft-Server-ActiveSync?Cmd=FolderSync&User=xxxxx@xxxxxxxxxx&DeviceId=EFB9B5DDB53843B5AA865100AA459178&DeviceType=WindowsOutlook15 HTTP/1.1" 200 498
      

      However, if I close Outlook and re-open it, I see a different Device ID in my Apache logs:

      x.x.x.x - xxxxx@xxxxxxxxxx [30/Dec/2021:01:30:18 +0000] "POST /Microsoft-Server-ActiveSync?Cmd=FolderSync&User=xxxxx@xxxxxxxxxx&DeviceId=E429C4ACF36A4108AFF029F8D3C503EF&DeviceType=WindowsOutlook15 HTTP/1.1" 200 13
      

      This causes major issues since Outlook tries to resync everything but fails miserably since z-push has no data associated with the new Device ID. I found that the Device ID is stored in the Windows registry at:

      HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Profiles\{profile_name}\9375CFF0413111d3B88A00104B2A6676\00000002\EAS DeviceId
      

      If I change the Device ID in the registry back to the original one, everything works from then on. Has anyone else run into this??

      I am using Outlook Version 2111 Build 16.0.14701.20254

        Hi @fkoyer,

        I am not sure how Z-Push should be able to trigger Outlook to change its device id.

        If you manage to replicate the effect on a different Windows installation, I would recommend to report this bug with Microsoft.

        Regards Felix

          Hi @fbartels,

          Thanks for responding. I know Z-Push isn’t causing the issue. I was just hoping someone else has run into the issue and had a solution or a workaround. If this is indeed a bug in Outlook then it would probably cause problems with lots of Z-Push users. If no one else is seeing it then I guess it’s just me :(

            Hi @fkoyer, observed the same: Outlook changes device ID after initial sync - same version as yours: Outlook 2019 (Version 2111 Build 16.0.14701.20254)

              Interesting, I’ve had it several times that outlook just stops syncing and just says it’s not connected. Perhaps this is the very same problem? I will check once this happens again if the ID has changed, thanks for posting the registry key this can be seen at!

                Have had this happening to me too, when setting up a new account.
                Using the Kopano Outlook extension I triggered a complete resync, which worked well and the ID has remained the same ever since.
