Apple Mail folders not displaying after moving from Exchange to Apple Mail
I am running a MacBook M1x with 13.1
I have moved my email from an exchange server to Apple Mail.
My online mail folders display correctly in all my email applications except Apple Mail and Outlook for Mac, in that they are completely missing from the folder tree except for the Inbox and a new Test folder I created. Outlook for Windows displays my mail folders correctly, Spark an email client on the App Store displays my mail folders correctly. iPhone and iPad display my email folders correctly.
I contacted Apple Support in October last year, they have run extensive diagnostic tests and have referred it to the engineers. Despite following up I get zero feed back or suggestions as to a resolution.
Anyone else have a similar problem, any advice welcome.
