Can M365 F3 license mailbox be configured with Outlook perpetual desktop client license

Question

Can M365 F3 license mailbox be configured with Outlook perpetual desktop client license. We understand Office cannot be activated with F3, but what if Office 2019/16 perpetual device based client installation is already done, can F3 mailbox be configured with the same. We know E1 could work with it.

Answer 1

Hi @GoodResource ,

Microsoft 365 F plans don't support using Outlook to access mail in Exchange Online through an Exchange connection.

To work around, you can set up Outlook to access mail in Exchange Online through a Post Office Protocol (POP3) connection. Please see: https://learn.microsoft.com/en-us/exchange/troubleshoot/outlook-issues/encrypted-connection-unavailable

You can, but this will still not allow you to use it like a "regular" mailbox, as there are server-side restrictions (i.e. blocked protocols).
