Lotus Notes 8.5 Calendar Issues

After migrating all of our servers “18” down from 59 to 8.5 and starting the upgrade to for the user to 8.5 client from 7.0.3 we are starting to see an error message when user schedule a meeting with multiple people. The error messages is “Field: ‘tmpUseLongDate’: Incorrect Data Type for operator or @Function: Time/Date Expected”

These are users that I have update their mail file with the 8.5 mail template.

Any Idea…

Subject: ‘Error trying to open document: Note item not found’ or ‘Field: ‘tmpUseLongDate’: Incorrect data type’ when opening meeting invitation

Having the same issue with one user.

Does anybody have a workaround for this?

Subject: TechNote says

However, additional reports of this issue were observed in Notes/Domino releases 8.0, 7.0.3, 6.5.5, 6.5.3 and 6.0.3. These occurrences were reported to Quality Engineering as SPR# RREN7DAH2L and have been fixed in 8.5.1.

so you should try upgrading to 8.51 or contact Tech Support about getting the fix on your specific release.
