Cannot add apps to Outlook Desktop

[PeterDKEU]

Hi

I have Microsoft 365 Business Standard - and use the Outlook desktop app for the 365 e-mail account and several non 365 accounts (IMAP/POP). When I click at the All Apps button in the ribbon when using the 365 e-mail account - I see apps and can add apps. However when I am using one of the IMAP accounts and click the All Apps button it says: "You don't have any apps yet - Select Add Apps to browse and install apps." The problem is that the Add Apps is not present.

Any idea how to fix it?

That's by design, AFAIK.

So I can only use apps for my 365-mail account - and not the rest?

Yes. Or you can try to find another way to install apps.
