After removing and re-adding the account as you did in your other question, does this error still appear?

Afraid so Gary

Doesn’t really make any sense to me because it says there is an error uploading items. If you removed the account from eM Client, then re-added it, there would not be anything to upload. Unless it is for a different account than what you removed for the other problem.

Afraid this will take the developers to sort out. If you have a Pro License you could open a support ticket.

Thanks Gary … When home later I will try again - many thanks once again

Gary - after I tried it again, the issue went away! Many thanks once again! Cheers.
