Folders disappeared after serverchange
 

I just changed setup on my iPhone native email client.
Now I use imap.fastmail.com and an app password.
But I discovered that I now am missing all folders besides Inbox.
Cant figure out what I am doing wrong here....
Help much appreciated

My first guess is that your IMAP path prefix is not set up correctly. See:

Apart from Bill's suggestion (definitely the first thing to check) it might be that the other folders are not "subscribed" and that your client is set up to only show subscribed folders.

Close then restart Mail app
 

I just tried this on an iPhone and now remember how it works. There is no tool to subscribe to folders, but this occurs automatically. If the IMAP prefix is correct, then just close Mail (remove from memory by double-pushing the button and swiping up on the Apple iOS Mail app). Then restart Mail and all of your folders should appear.

Got it....
 

Ahh stupid me did not try and restart mail app...

It is now working like before.

Thx Bill
