Users Cannot Access Share Calendars After .Net 2.0 SP2 Installed on CAS

Hi All,

I am having a very furstrating problem where *some* users are unable to view shared calendars, Outlook crashes.

I have had a brief look at this issue and it would seem to be related to .Net 2.0 SP2 installation, but it is not affecting all users.

Those users it is affecting are able to view shared calendars that they added to thier list before this upgrade, but trying to add any new ones crashes Outlook (2010).

I have removed .Net SP2 from the CAS server but this has not resloved the problem, I'm a bit stuck.... does anyone have any further ideas?  

I did find an article regarding this on Technet but the hotfix seems only to be avaliable to users with support agreements with Microsoft......obviously I am cautious about downloading this from a 3rd party.

Does anyone have any ideas...?

Do the Client PCs have Office 2010 SP1 installed?

If not try installing it and try again

Altetnativley, would try to remove and recreate a 1 users profile on a mahcine to see if it resolves it

I can only find a link where they want me to pay £199 for a support call!  Do you have a link to the sign-in page?

This is starting to annoy me now :(

I was expecting a page with "download hotfix page\link" on the KB.

Now, double-checked that they want to get a support call to get the hotfix
(you can check with them ...IMO, hotfix requests should not be charged?)
techmissAuthor Commented:
Yep, I called them and to their credit they were pretty helpful - said they would send me a link within 8 hours with the hotfix download location.

I'll close this thread now (hopefully the hotfix will FIX the issue)
