Pushing Android Outlook emails to O365 server email account

[H <ag...@me...>]

Although mbsync is only indirectly involved, it might still be a tool to accomplish this.

I have a bunch of emails in Outlook for Android from a temporarily suspended account O365 account. Once the account is again available and the available backup on the server side has been restored, the email I have in Android Outlook will likely not be among the ones restored from the server side backup.

I am curious if it will be possible for me to later push my Android Outlook emails back to the O365 server? Clearly once I reconnect the Outlook O365 account to the server they will disappear from the phone as well but until such time they still exist on the phone.

Can I (1) get them out of Android Outlook into eg. mbsync format, and then later (2) push them to the server O365 account using mbsync?
