A caution in using a PST with both Outlook 2010 and an earlier version

[Brian Tillman]

I have a dual boot PC at home. One partition uses Windows XP and
Outlook 2007, with a PST kept on a second drive. The other partition
uses Windows 7 and Outlok 2010. I reference the same PST in that
version of Outlook as well. This works fine within the two Outlooks
until one tries to sync with a Windows Mobile 2003 PDA running
"Microsoft Pocket PC Version 4.20.0". I sync the Windows XP/Outlook
2007 installation using ActiveSync and I also sync that same PDA with a
Windows XP/Outlook 2003 system at work. I've been doing this literally
for years, with, first, Outlook 2003 on the home system, then with
Outlook 2007 beta, then the released version of Outlook 2007 with no
problems, prior to accessing the PST from Outlok 2010 as well.

Since I started using the PST with both the Outlook 2007 installation
and Outlook 2010, new calendar items added on the work PC in Outlook
2003 and synched with the PDA will not properly sync with Outlook 2007,
stating that the form contains improper values. Non-calendar items sync
fine. I conjecture that Outlook 2010 has altered the calendar records
form in such a way that doesn't bother Outlook 2007, but does bother
Pocket Outlook. I don't expect anyone to solve this problem - I'll
probably solve it by giving each Outlook its own PST again - but I
wanted people to know about it.

I may discovered the issue and I have fixed this problem. Usually
form errors can be resolved by clearing the forms cache, so I entere
the Forms management wizard. There I discovered I still had the Liv
Search Maps add-in installed on the XP partition. Unlike many people,
never had problems with this add-in and never uninstalled it. However
I used it so infrequeently, I simply forgot about it and never had
problem before. I cleared the cache, then deleted the add-in.
Following that, my Windows Mobile PDA synched right away. It could b
that simply emptying the cache would have sufficed, but certainl
removing the buggy add-in didn't hurt
