Question : Outlook 2003 exchange duplicate calendar issue
|
|
Hi - on behalf of one of my clients who has told me to do whatever to rectify the issue!!
Scenario in place:
SBS2003 SP1, Exchange SP2 - 2 desktops in Office and 2 laptops that VPN in. All machines XP SP2 running Office 2003 Pro SP2. Fully patched with windows updates and Microsoft office updates Post SP2
Issue:
A little difficut to describe the scenario but bear with me. There are two instances of Calendar within Outlook and therefore the PA and MD are constantly writing to both (by mistake). The main Calendar in the Folder List should be the default one and not have the option to be deleted. But if I right click the calendar file it does give me the option to delete it.
The second calendar is a sub directory of Contacts. So if I click Folder List within Outlook and expand Contacts, there is an instance of Calendar there. If I right click this one, the delete option is geyed out which gives the impression that is the default instance and has sonmehow moved under the contacts folder.
I have removed and rejoined the machine from the domain, I have deleted the Offline folder and exchange account and re-added them back in but once the mailbox resynchronises with Exchange server, both instances are back in again. I have not deleted the profile because if I have to, I will have to delete the profile on all 4 machines as they all see this configuration.
When I go for the option "Remove from my calendars" this has no effect. The MD just wants one instance of the calendar so there is no second guessing whether he or his PA is writing to the correct one or not. The main calendar on the root of the Folder list should be the one that syncs with his PDA using Windows Mobile 5
If anyone has any thoughts on how to make the root calendar have the correct properties and remove the calendar under the Contacts sub folder I would be very grateful as this has been going on for 2 months now. There are all away on Easter so I can delete profiles comopletely on all machines if I have to but I have a feeling that this maybe eminating from exchange but I don't know where to look to delete the rogue calendar instance!
Thanks for reading
Regards
Robin

Answer : Outlook 2003 exchange duplicate calendar issue

I hadthis issue, and i consulted the MCS and he solution was to exmerge the account to export emails, delete the mailbox create it again and exmerge to import the emails back.
this ccurs due to a discrepancy in the replid map in the memory on the server and the replid map in Jet. Such issues are common due to the GRM (Guid/replid mapping) cache being on by default in SP2 (whereas in SP1 it was turned off by default). Remounting the MDB or restarting the Store service will resolve the crashes for affected users. Some users that have experienced the crashing problem have also encountered problems with duplicate default folders, delegate issues, as well as Free/Busy problems. These problems persist after the restart and must be manually corrected.
You can also perform the following steps to disable GRM cache on Exchange 2003 SP2.
1. Access the Registry: Click start -> Run
-> Type "regedit" and hit OK
2. Locate the following subkey:
HKLM\System\CurrentControlSet\Services\MSExchangeIS\
\\
3. Add the following value
Value: Guid-Replid Caching
Type: REG_DWORD
Value Data: 0
NOTE: You should set "Guid-Replid Caching " for all stores you wish to disable the GRM cache
