Our users are unable to use the Outlook To Do app in the Outlook desktop client.

It gives the error "There was a problem connecting to this app". Just doing a quick Google search it looks like a widespread problem. I have a ticket open with MS but no answers yet.

It does work in the Outlook online app.

    Reset the Office cache, it should fix the problem:

    1. Close Outlook
    2. Rename or Remove these two folders: %LOCALAPPDATA%\Microsoft\Office\16.0\wef %userprofile%\AppData\Local\Microsoft\Outlook\HubAppFileCache

    Re-open Outlook and click the "To-Do" shortcut, and it should open without issue.

    This fixed a user we had. Thank you for this.

    This fix was attempted and it did not work for me. On the latest version and build of Version 2307 (Build 16626.20170)

    My client got updated to the version below and the To Do does not open up but gives the same error. Microsoft better look into this, I am getting more users that are frustrated.

    Update: Not sure what happened tried it again this afternoon and it is working. I will see if it is also opening on the rest of my users clients.

    Yes, this is the response I received from MS.

    Unfortunately, the ToDo app was hard coded into January release of Semi-Annual channel in a way that engineering cannot disable it on the backend. Due to this, engineering made the decision that the best thing to do was move forward with enabling the To Do client app to be able to work with GCC Moderate accounts.

    I understand that the fix is was included in the Version 2303 which (Build 16224.20000) was released to the Beta Channal on February 28, 2023 and Version 2303 is expected to be released into the Current Channel: April 11, 2023.
