So I have been running into this issue every so often but now it happens almost everyday on one of my users computers.
Here is the problem. The user is using Outlook 2007 and has multiple calendars open that she views at different times during the day. 3 are public folder calendars that have been added to favorites that are shared among most of the users in the office. Two others are shared calendars of two other users that she needs to view every so often.
Off and on over the past few months we have had an issue where this user will go click on the calendars button on the left and will find that all or most of her shared and public favorited calendars are not listed. She can go back and manually add them but it has become incredibly annoying this past week because it seems to happen every day now.
I have found two solutions that have only temporarily fixed this issue. One is to launch outlook with the /resetnavpan switch. This does restore the calendars to the list but a day later they will be lost again.
The next option was to rename the .xml file in the appdata folder for Outlook and reopen outlook to have it create a new one. This does work but again only temporarily. I was using the instructions found on the following link to do this: http://blog.palehorse.net/2007/09/26/outlook-ate-my-favorite-shortcuts/
One thing I will note about the second solution was that it didn't exactly follow that I had to re-add all of my favorites after renaming the .xml file. Instead all the shared calendars just reappeared after renaming and launching Outlook 2007. Not exactly what the instructions from that link had described.
I have also seen solutions that mention installing SP1 if not already installed. I am running on SP2 right now so I have already covered that idea.
I have been searching for a solution for this but I haven't found the right one yet. Anyone have any suggestions?
Thanks in advance.
