Calendar reminders from former delegate account

Question

Calendar reminders from former delegate account

Bob Braun 0

I have been receiving random Outlook calendar reminders from a user account that was delegated to me when they left. Sometime last year (2025) I removed the delegate from that account. But I still randomly have the reminders pop up on my screen. When I try to delete the appointment I get an error message that says "you cannot make changes to contents of this read-only folder".

How do I find that folder and remove?

Hi Bob Braun

From what you've described, I would first recommend checking the Calendar section in Outlook on the web to confirm whether the former delegate's calendar is still added there. If it is, removing it may help determine whether it is related to the reminders you are receiving.

You can also try resetting the Outlook reminder settings. In Classic Outlook, press Windows + R, then run the following command: outlook.exe /cleanreminders

This will clear and rebuild Outlook's reminder information.

If the reminders continue to appear after these steps, I recommend reaching out to your IT administrator for further investigation. They can use the following PowerShell command to review the calendar permissions on the former delegate's mailbox:

Get-MailboxFolderPermission -Identity <Delegate>:\Calendar

If there is still a permission entry associated with your account, they can remove it using:

Remove-MailboxFolderPermission -Identity <Delegate>:\Calendar -User <YourEmailAccount>

I hope this information helps point you in the right direction and provides some additional insight.
