Outlook 2007 and ModCal folders

I, too, am having a calendar issue. There are now hundreds of _ModCal#### calendars on my computer....and I've only sync'ed my iPhone with my computer three times.

While I can delete these calendars...I can only delete them *one at a time*. And since they're multiplying like rabbits, it's extremely frustrating.

Does anyone have insight into how to get rid of these pesky calendars?

I wish I could do this too. I have thousands of ModCal calendars and it's really annoying. I tried to delete them all from the ~/Library/Calendars directory, but they just keep coming back!

Me too! Just hoping an answer shows up one day

You can reset the folder permissions using a command line.
Try this:
Click on Start, Run, type Outlook.exe /resetfolders and click ok. That should allow you to now delete the _Modcal*.Calendar entries.

I have the exact same problem. And the solution proposed here did not work. /resetfolder ran properly, but I still don't have the authority to delete the folder.

But, even if I did. I think once I sync my iPhone again they will appear again. Does anyone know what is causing the problem in the first place?

I am having the same issue, if anyone has a fix, it would be very helpful. Thanks
