Hi,
We have a issue where we enabled remote mailbox for user and it doesn't populate in Office 365. We have this message "We are preparing mailbox for this user" message in office 365.
We again disabled the remote mailbox, wait for 2 syncs, enable the mailbox, wait for the sync, set archive guid and then i left it for entire day and magically the mailbox appeared in Office 365.
But a new problem started as the guid of Office 365 mailbox is different than On-prem mailbox. I tried various ways to connect both of them and was not successfully.
Any suggestion would be appreciated.
Thank you.
