i am aware there is a mismatch on one of the servers but there does not seem to be a clear cut way to find the offending file to delete it or force a backwards sync ?
How would i identify what GUID f982a82747469869ea0f0100cf58dcff means?

This command should at least tell you which mail folder exhibits the issue
doveadm mailbox status -u "faye@scom.ca" guid "*" | grep f982a82747469869ea0f0100cf58dcff
Once you know the mailbox folder/name, look at the stats and drill down from there. Let's say the folder name is 'Saved Notifications'
doveadm mailbox status -u "faye@scom.ca" all "Saved Notifications"

I just wanted to provide an update as the replication issues are now resolved
i thanks you again for showing howto translate a GUID into a folder name however that did not provide enough info to cause a resync
it turns out all you have to do is manually delete the offending folder on the replica server and dovecot will resync immeditely
standard case of over thinking the issue.
hopes this helps someone else down the road when dsync throws reversal errors.
