Error Synchronizing Folders

[GPaul]

I am getting the following error message when folders are synchronized:

23:29:15 Synchronizer Version 12.0.6315
23:29:15 Synchronizing Mailbox '{username}'
23:29:15 Synchronizing Hierarchy
23:29:16 Error synchronizing folder

Do I need to change the type of Archive file I am using (OST? PST?) Or is it
another issue?

Thanks in advance,

Paul
