Hello, my Mac is running on a Tahoe 26.2 and I can't open Outlook without getting a "repair" message box. If i press "repair", nothing happens and the box reappears. I haven't been able to open the app for as long as I remember. I tried pressing "Option" on my keyboard while opening the app as suggested to rebuild the data, nothing happened. I also tried looking for contents in finder with Command+Shift+G and nothing came up. Does anyone know how I can fix this? Thank you:)

    I would first try creating a fresh Outlook profile without opening Outlook: open Finder > Applications, right-click Microsoft Outlook > Show Package Contents, then open Contents > SharedSupport > Outlook Profile Manager. Create a new profile, set it as the default, and try Outlook again.

    If it doesn't work, please post a screenshot of the exact Repair dialog, because the wording may identify whether this is an Outlook profile/database repair prompt or an application/installation problem.
