Exchange 2016 User Mailboxes Migrated to Exchange 2019 | IMAP | SMTP Permission
We have migrated from Exchange 2016 to Exchange 2019 Servers. Exchange 2016 servers have been shutdown now. When I initially setup a new servers, i created a new user and mailbox for each server...
Does this problem occur for newly created messages? When doing upgrade (Exchange 2016 to 2019), all you need to do is migrate the mailboxes from a DB on Exchange 2016 to a DB on Exchange 2019, and all the configuration is retained. From your description, it sounds like you've created new mailboxes and exported/imported messages to these new mailboxes
