I having some major difficulties convincing upper management that the version of exchange we are running is no longer supported by Microsoft, and that there are no DST patches to fix our calendar issues. Do you people know of any patches that may be a work around?

Have you been asleep for the last few weeks? The DST issue has been extensively debated on many online forums. What particular DST issues are you seening?

Well for starters, calendar entries are disapearing... Enter it in the morning, and by the afternoon....gone.

Plus, calendar entries that were entered months ago, just disapeared.

I've not heard of calendar items disappearing as a symptom of DST-related issues. http://support.microsoft.com/kb/178630 has details of how to set up Outlook so that Calendar items that are deleted manually can be recovered from the dumpster - I'd enable this on the problem workstations so that when items disappear you can rule out manual finger trouble. Give us more details of the problem: number of servers, patch levels, number of mailboxes in total, number of affected mailboxes, first occurance of the problem, details of any anti-virus s/w running, etc etc. What DST-related changes have you made, if any? What OS are your 5.5 servers running on? Did you make OS-level timezone changes as per the TZEDIT fix? What are your clients? If XP, have you implemented the XP client DST fixes? Any OWA in the mix? Any POP3 clients? I would have thought a few minutes with Google would turn up myriad references to Exchange 5.5 support being unavailable from MS. Just the fact that Exchange 2007 is now RTM is enough (it's 3 versions further on than 5.5), surely?

I went to all 2000 workstations and ran TZedit.exe, and modified it accordingly. Then I ran the XP patch, that does the same thing. I then did the TZedit on all of my 2000 servers. We are running Exchange 5.5 SP4 on 2000 server running SP4. OWA is in the mix, and no POP3 users. I've wanted to switch many years ago to Exchange 2003, but we don't have the $$ for it right now. I can't imagine migrating version 5.5 to exchange 2007. I would assume that you need to be running 2003 server, and that too needs to be migrated from a 2000 domain to a 2003. Another reason why it has not been done.

You didn't answer all my questions. I've still no idea whether all your users are having problems, and how many that would be. OWA is probably broken for the duration of the extended period, ie until the first weekend in April. It will break again in the fall. When I say broken, appointments will be an hour out for these periods. That's because you really need a CDO patch for Exchange 5.5 to fix the OWA appointments clock. Just changing the clients and server OSs with TZEDIT isn't enough. (Incidentially, did you know there were free 3rd party tools that would have enabled you to make these Win2000 OS changes much more easily?) I'm not beating you up regarding still being on 5.5 (I have lots of clients that still are!); but this is part of the leverage. The company has 'saved' loads of money by not upgrading - but is it really saved? Or have they just defered the cost? It's part of your (the IT function) job to inform and educate the purseholders regarding the repercussions of their decisions. You may or may not be able to influence the decisions, but they need to undersand the implications of the decisions they make year on year. Every time you make a recommendation (in writing) you need to include a section on the costs and repercussions of not accepting the recommendation - and roll these commulatively if they turn you down year on year. As you say, it's now going to be very difficult to migrate from 5.5 to 2007 straight off, so you're probably going to have to go via 2003 eventually anyway, even if just as a migration transition.

Only two people are having issues in regards to appointments disapearing. Averyone else is off an hour. Was not aware of the 3rd party tools. Then again, I never new there were others like me that still run Exchange 5.5. :0 Any how, I don't have a CSA, therefore I can't obtain the CDO patch. I guess I have to google it and see if anyone has it available for download.

Joeteck -> RE: DST and Exchange 5.5 (22.Mar.2007 10:24:55 AM)
Found the CDO patch... but it was applied already....

zbnet -> RE: DST and Exchange 5.5 (22.Mar.2007 11:06:36 AM)
The disappearing calendar items are not DST related - look at delegates, calendar permissions, laptops/offline working, OWA access to these mailboxes, blackberry use; add the DumpsterAlwaysOn reg entry as per my first response.

Joeteck -> RE: DST and Exchange 5.5 (22.Mar.2007 11:40:09 AM)
OWA is not used everyday. Dumbster.reg has been applied since 2003. Looking into delegates & permissions...
