Calendar Overlay - Cannot complete this action. Please try again

Question

I have a rather strange issue this morning.

Running SP2010.

One I attempt to add a Calendar overlay to an existing Calendar, I get an error:

Cannot complete this action. Please try again.

The URL which i'm entering is definitely correct. I've tried with the Friendly DNS Name and with the Server Name : http://mysharepoint/site ; http://server1/site. Both giving the same error.

Here's the catch though. Calendars on my Rootweb/Top Level Site works fine.

This all started after installing Service Pack 1 for Sharepoint 2010.

ULS Is throwing the following exceptions:

VtemplateManager::loadUncustomizedFormSchema failed with error code 0x80004005.

and

Any ideas?

Answer 1

Ok, I found the answer. For some reason , the Team Discussion List was broken on all the WEBS where I coudln't add the calendar overlays. Also, the Site content and Structure page was not opening. Thanks to this fix here: http://www.office-outlook.com/outlook-forum/index.php/m/607651/#msg_607651 I managed to fix the problem by deleting the "Team Discussion" List. I have no need for it, so I didn't restore it.
