All of a sudden, the dashboard started crashing and naming the office 365 add-in as the cause. Is there a way to re-install that add-in? I can't think of anything else to do. If I disable it through safe-mode, the dashboard starts up fine but the Office 365 is missing, which I badly need. Any ideas?

    Hello there,

    Check the Dashboard.log file (%ProgramData%\microsoft\windows server\logs). Besides, please check Event Viewer and confirm that if there is any relate event has been logged.

    If possible, please disable 3rd party process temporarily, re-start system in Clean Boot and confirm that if tab will crash again.

    Besides, please try to verify the installation state of .Net Framework – tool and step mentioned in blog “.NET Framework Setup Verification Tool User’s Guide”:
    https://blogs.msdn.microsoft.com/astebner/2008/10/13/net-framework-setup-verification-tool-users-guide/

    Open Dashboard – Settings – Safe Mode, disable Users tab, close and re-open Dashboard, re-enable Users tab, close and re-open Dashboard to check the result.

    Hi @IT volunteer

    I believe this may be because it has been depreciated.

    Thanks for the reply and the suggestions. To be clear, the dashboard does come up if I disable the OFFICE 365 add-on. I followed all your recommendations and got the following:

    • dashboard log: it shows that it crashes around the SharePointUser loading (??). Here's what appears to be the relevant part:

    [15124] 220816.155905.7450: O365Manager: TResult : SharePointUser, args : Microsoft.WindowsServerSolutions.Common.ProviderFramework.OperationInvokeEventArgs1[Microsoft.WindowsServerSolutions.O365Integration.SharePointUser] [15124] 220816.155905.7460: O365Manager: actualArgs : Microsoft.WindowsServerSolutions.Common.ProviderFramework.OperationInvokeEventArgs1[Microsoft.WindowsServerSolutions.O365Integration.SharePointUser]
    [5156] 220816.155905.7480: Dashboard.Forms: !!!!FATAL: Dashboard shutting down due to unhandled exception: One or more errors occurred.
    [5156] 220816.155906.0742: Dashboard.Forms: System.AggregateException: One or more errors occurred. ---> System.ArgumentException: An item with the same key has already been added.
    at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)
    at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
    at Microsoft.WindowsServerSolutions.O365Integration.SharePointLibraryManager.<RefreshSiteUsers>d__68.MoveNext()
    --- End of stack trace from previous location where exception was thrown ---

    • "If possible, please disable 3rd party process temporarily, re-start system in Clean Boot and confirm that if tab will crash again.": I'm not sure what you mean by this
    • .NET fix: nothing came up as a problem
    • Open, closing, turning off "user", etc. didn't do anything

    Any other suggestions?

    SOLVED: thanks to @Limitless Technology , I was able to get a better idea of what might have been happening. After I was pointed to the log file and reading it in detail, it looked like a user account had failed the AD sync. I went thru a number of accounts on the Azure AD and noticed that one account had been created twice. I deleted the one that didn't have any login info and that did it. I waited for the sync to automatically happen and that took care of it.

    thanks!
