Opening Calendar (or shared calendar) Causes Outlook to Shut Down

Hi Team,

We recently rolled out a Hosted Exchange solution to replace our local Exchange installation. Since then when users (more by the day) click on a calendar (some people it's their own, others it's a shared calendar) Outlook shuts down completely and asks if we want to re-open it. You do this, click the calendar, and the same thing happens.
Running Outlook 2007 in cached exchange mode.

If we run Outlook with the /safe switch it fixes the problem.
If we run in any of the safe 1/3/4 switches it doesn't fix it.

Anyone got any ideas? We can't figure it out....

Thanks

This was a problem with the hosted exchange partner, they were able to remotely resolve it, no idea how.

Add ins - it's only got NOD32, but we disabled that Addin and excluded OST's from it's scanning.
Latest SP indeed.
They're fresh installs of 2007, updated (were on 2003).

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Nope. Tell me why that would be a good try and what to do if it works?

It would prove an add in is at play here, then you need to Untick the add-INS then start outlook normally, if it works then tick the add/INS one by one till outlook dies,  then you know what add-in is causing the issue.

Otherwise you could export the Calender to PST then view the Calender in the PST and verify it works, if it does, then delete all items in the mailbox calendar, verify it can be opened now and then re-import the Calendar from the PST and verify it works
