I have a user that shared an Exchange 2003 public folder calendar via calendars.office.microsoft.com and that user has left the company. There are continual prompts for all network users for credentials to access this shared calendar. I need to remove this calendar from being shared through calendars.office.microsoft.com but without the initial credentials, it seems this cannot be "unshared". I have spent a great deal of time looking for an answer and a solution but have not found any direction. How can I remove this public folder calendar from being shared and how can I prevent this from happening again ? Thanks. Ed

Yes, that looks like it could be a predicament. Have you configured the folder itself to be unshared as described in the section entitled "Remove your calendar from Office Online" in the following article? http://office.microsoft.com/en-us/outlook-help/change-settings-or-remove-calendars-published-to-office-online-HA010044370.aspxEd Crowley MVP "There are seldom good technological solutions to behavioral problems."

I've tried that repeatedly but am prompted for the users credentials, which I don't have, to remove it from ofiice online.

Hi, The following similar issue for your reference. need to delete public folder calendar item but unable: http://forums.msexchange.org/m_1800488878/mpage_1/key_/tm.htm#1800488918 Wendy Liu TechNet Community Support

I'm not following the suggestion because I have a public folder calendar that was shared to calendars.office.microsoft.com and need to stop the share. Deleting the PF calendar is not the problem. The user that shared this calendar has left the company and we don't have the initial credentials to "unshare" from calendars.office.microsoft.com. Ideas ??

Any reason why you can get the intial credentials?Sukh

Hi Ed Norman, You can use PFDAVAdmin tool to change the calendar owner to a special user, and use the special user manage calendar. You can refer to above link I provide.
