Users cannot open other users calendars after Exchange 5.5 to 2003 Migration
Posted on 2004-09-07
Rolled out Active Directory and migrated to Exchage 2003 (from 5.5) this weekend for a 100 user company. Everything seems to be going well except for this one little quirk. Users have always had rights to view everyone else's Calendars, as well as one group has the right to view & edit everyones contacts. The permissions were assigned by opening each users calendar permissions from their outlook and adding in the "everyone" distribution list and assigning the appropriate rights. Same for the contacts, our "contact group" was given edit permissions to all users contacts. Everything worked fine in the 5.5 world, until we added in the Exchange 2003 server.
We currently have both our Exchange 5.5 and Exchange 2003 Servers running, replicating (as Microsoft recomended we do until all users have logged in at least once to get the updated settings - then remove the 5.5 server). However now no one can access anyone else's calendars or contacts. We get an "Unable to display the folder. The Calendar folder could not be found." error. We found that we could give individual users permissions to other peoples calendars and they can access it, but it seems to ignore the "everyone" group that is setup. If we try to add any group to someones calendar (including removing and re-adding the "everyone" group) we get the following error:
"The modified permissions could not be saved. The client operation failed."
