I have a client who I migrated to O365. They were previously using an email account provided by Spectrum/Road Runner that was set up on their PC in the Outlook desktop app as IMAP.
I exported the Road Runner emails into a PST file. I then set up a new custom domain and email in O365 then added the O365 email account (using a new Outlook Profile) to Outlook desktop. I then imported the Road Runner PST file into the new account.
On the Outlook desktop app, I can see all the emails and email folders that were imported into the new account. When I check my client's iPhone (which I also set up the new O365 account) I do not see any of the imported emails or folders.
Can someone assist with fixing that?
