Help stop this in log: Error reading OperationTime for folder operations: xxxxx.nsf: Invalid Time or Date Encountered

I am getting repeated " Error reading OperationTime for folder operations: xxxx.nsf: Invalid Time or Date Encountered" errors on the consol and log file.

Tried different ways to fix this with limited success, but the main problem is it is filling up the log file, is there a way of stopping this reporting so much, or at least hide it?

The user OS time must be ahead , and one of the sent mailmust having the future time

you need to create a new replica of the database and replace

it with existing mail file

Correct some have sent mail ahead of the correct time, I can’t delete these emails though, and it’s difficult to get hold of the users (not in this country) to change their pc time setting, but in the mean time the server logs are filling up with these errors.Not quite understand the fix for this though.
