>>>Hi everybody,
>>>
>>>In my Outlook I have the old account I don't have access to anymore. It still keeps asking me periodically to login and it still brings all old notifications from the Calendar. How can I disable that, please? I do want to be able to read my old emails to that account, but I don't want to get any activities and I don't want to being prompted for the password.
>>>
>>>Thanks a lot in advance.

It maybe be your principle account, if you switch main account to another account, you maybe able to delete that trouble one.
