How do I access shared mailboxes?

[Babasach]

Hi!
I'm in the process of setting up Aqua Mail to approximate my usual work setup.  I can access the folders for my main address,  but I can't seem to find where/how to subscribe/access the shared email accounts (I have about a dozen).

Would anybody know how to do that?

Thanks in advance for your help!

Exchange / EWS?

There is a setting when adding an account, tap Manual and enter the shared folder's name on the next screen.

For an existing account, long press it (the account) and choose Account setup.
