hello
extually it is not stuck, just slow, emails in the queue still being increase and some times later, so of them being cleared but not all, then loop as this, from user side they feel slow to update the folder, i just check all email in mapidelivery queue, looks like all emails are send to this server and waiting for being write into database.
for the database i think is healthy, status looks fine, and all services are running.
for error you mentioned i can't find it, because all queue items are in ready or active status.

untile now i have uninstall Mcafee then reboot server, but not helpful either.

so what i can do next?

thanks

make sure users are connecting through cached exchange mode.

Check the I/O latency of the database drive.

Verify the header to find out where the mail got delayed.

Databases in the local AD site.
