I am running Outlook 2010 for an IMAP account under Windows 7 ultimate, and have just migrated from Outlook 2003, also IMAP, under Win/XP/SP3. Account includes emails, calendar, tasks and notes. The problem is with processing task reminders in right hand panel in OL2010..

The tasks were all set up some time ago in OL2003, and when complete were deleted or marked as complete. on OL2003 For recurring tasks of course, this results in a new task being generated on the correct date. As part of migration to 2010, I attached the 2003 PST file containing the tasks to the 2010 account, and then tried to process all the tasks within OL2010. As I expected, those which I had not deleted beforehand showed up as overdue, but when I tried to delete them or mark them as complete, either singly or several at a time, I get the error message " failed to update headers" .

Checking technet, I found a suggestion to run scanpst.exe. I did so (using the office 14 version of scanpst) and it found some errors in the pst file containing the tasks folder and corrected them. But when I restarted OL2010 and tried again to process the outstanding tasks, the problem recurred.

I tried to resolve this by COPYing the relevant task folder from the OL2003 pst file to the corresponding OL2010 pst file, rather than allow 2010 to have direct access to a pst file originally created in OL2003, but this didn't work - same problem.

Contacts, calendar and notes have all migrated successfully by directly attaching the PST file to the 2010 account, and of course emails were migrated by IMAP, so it's a shame that tasks cannot move in the same way.

Any ideas please?

Clarify this statement, " migrated successfully by directly attaching the PST file to the 2010 account." State specifically what you did.Russ Valentine

When I created the new OL2010 IMAP account, the usual two pst files were created, one for calendar, contacts etc and one for synced IMAP email . From within OL2010, I added my existing OL2003 pst file which contained my old tasks like this: file tab - account settings - account settings - data files - add, then browsed to the correct OL2003 PST file and clicked OK. Then closed OL2010 and re-opened.

OK?

I would have connected my previous file first instead of letting Outlook create another one. Outlook 2010 lets you do that when you use manual configuration for a new profile.Russ Valentine

Thanks - your suggestion didn't make any difference, but I've bypassed problem by ignoring the to do list. OL2010 seems to polulate the to do list (which I think is a new function?) with outstanding tasks and reminders from OL2003. It treated all my old reminders as to do items when I had not created them as that. I solved my problem by removing the " task list" from right hand bar - rclick on blank space under the calendar.

I can now see outstanding tasks on the Outlook tday screen, or by viewing the tasks folder; either of these solutions is fine.
