DUA is generating error: "System.NullReferenceException: Object reference is not set to an instance of the object"
说明
DUA is generating error: "System.NullReferenceException: Object reference is not set to an instance of the object. at OutlookAgentLib.TeamsBase.IsActive(String teamsAppname) at OutlookAgentLib.NewTeamsConfiguration.IsActive()"
原因
The issue is caused by mixing different Teams versions and new Teams is not configured. For example: there is a Default Teams install for a private account. Then there was classic Teams and then “New” Teams.
解决办法
To resolve the issue, please fully configure the new Teams and run DUA again.
