Hello @BBJumpingBean
Outlook for iOS can be configured with an App config in the Managed App.
Everything you can configure is available here
App Config Keys
Thank you @cubandave - i've managed to get the config in place but i'm not having any luck locking down the Outlook app (more email accounts can still be added to the app). Do you happen to know any caveats to this working/not working? As in... you must use Exchange Online or the device must actually be in InTune? Here is a snip of what I have in place right now:
<key>IntuneMAMAllowedAccountsOnly</key>
<string>Enabled</string>
<key>IntuneMAMUPN</key>
<string>$EMAIL</string>
</dict>

More information about this restriction is available here.
“This capability is supported with Microsoft 365 and Office 365 accounts or on-premises accounts using hybrid modern authentication”
So if the mail accounts are not Office 365 then it will not work.
This works for me, users are not able to add "other" accounts into outlook for ios
<key>IntuneMAMAllowedAccountsOnly</key>
<string>Enabled</string>
that setting sort of works... in testing it appears users can add a personal account if added before a corporate account. Once the corporate account is added the personal account goes away and additional accounts aren't allowed thereafter.
I am experiencing something a bit different, I had a corporate account then added a personal account, and then applied this key via app config. Now I am not able to add any more accounts but the personal account stays it does not remove
