Unexpected one-minute startup of Outlook if UE-V is enabled
This article helps resolve an issue where you experience an unexpected one-minute delay for Outlook to start if UE-V is enabled in Windows 10, version 1809 or a later version of Windows.
Applies to: Windows 10 – all editions
Original KB number: 4569308
Symptoms
Consider the following scenario:
- You're using Outlook 2019 or Outlook 2016 on a computer that is running Windows 10, version 1809 or a later version of Windows.
- You install a cumulative update for Windows 10 that is released after March 17, 2020.
- You deploy User Experience Virtualization (UE-V) that has the Sync Method set to None.
- You register the MicrosoftOutlook2016CAWinXX.xml UE-V template. For example, you register MicrosoftOutlook2016CAWin32.xml.
In this scenario, Outlook takes one minute to start and display its splash screen.
Cause
This issue occurs when the UE-V Sync method is set to None. This setting causes Windows to ignore the synchronize timeout (by default, two seconds). Therefore, UE-V times out after one minute.
Resolution
To resolve this issue, use one of the following methods:
Method 1
Use the default Sync method SyncProvider.
The Sync method None is specific to workstations that have a permanent network connection to the SettingsStoragePath.
Method 2
Download and replace the version 3 of the Outlook custom action UEV template from the download center UE-V OutlookCA template update
