We have a small company with on-prem Exchange servers. The CEO wants us to migrate the mailboxes to Exchange Online from on-prem, because of the high availability system, management, etc.
Experts out there must be using Exchange online and will shed light on my question.
For example, MS has an issue and Exchange online is down for a day or a few hours.
Is there any third-party company that stores the incoming mails and forwards it to Exchange online? in this way, we can still get a new e-mail.
