Hi,
Will the deleted message disappear from the other Mac if we wait for enough time?
Have you tried right clicking the Inbox where the deleted message is originally located and click 'Synchronize Now'?
Besides, we may also try to clear the cache of your Inbox folder and then see whether this issue continues. To do this, right click the Inbox folder, select Properties. Under General tab, click
Empty Cache button.
Please let us know the result.
Regards,
Steve Fan
