shows same error on both servers
Server 1 :
sync faye@scom.ca
doveadm(faye@scom.ca)<90952><BJq9J2dHmGlIYwEA0dxyZQ>: Warning: Mailbox changes caused a desync. You may want to run dsync again: Remote lost mailbox GUID f982a82747469869ea0f0100cf58dcff (maybe it was just deleted?)
Server 2:
sync faye@scom.ca
doveadm(faye@scom.ca)<90952><BJq9J2dHmGlIYwEA0dxyZQ>: Warning: Mailbox changes caused a desync. You may want to run dsync again: Remote lost mailbox GUID f982a82747469869ea0f0100cf58dcff (maybe it was just deleted?)
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?
same on both servers.
doveadm force-resync -u faye@scom.ca '*'
have tried reindex etc etc etc issue persists
logs ??

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"
