I used to have a secondary Microsoft account that I created for the sole purpose of sharing a calendar with others.

The calendar was shared with my primary Microsoft account, which is a co-Owner of the calendar.

The secondary account fell into disuse and was apparently deleted after a period of inactivity, which is fine, it was no longer needed.

The problem I have is that the secondary account's shared calendar still shows up in my primary account and pops up in my Outlook, in the web based calendar and on my phone.

I wanted to get rid of it and when I tried to log on using the secondary account to unshare the calendar and close the account, I found out that the account had already been deleted.

Now I do not know how to unshare or otherwise get rid of this calendar, I do not want it to show up in my primary account anymore.

I would appreciate any help with this.
