How do I prevent Outlook 365 on the Mac from launching the New Version

This "New Outlook" for max is a steaming turd still (2 years later) missing most of the actual productivity features that were evolved into outlook over nearly three decades.

I so agree. Thanks. Who needs it!

This "New Outlook" for max is a steaming turd still (2 years later) missing most of the actual productivity features that were evolved into outlook over nearly three decades. Also, the waste of space is enormous. It requires constant re-authentication against other OATH endpoints (like google) and the constant force enabling of it is cumbersome at best.. It has to be disabled, then all accounts AGAIN re-authenticated. STOP SHOVING THIS **** DOWN OUR THROATS.

I will add that the new tact to try and force Microsoft Authenticator signup on every login is more of the same. I don't want to use your authenticator, I already use another service for MFA and it is setup in my account. STOP FORCING THIS **** ON US. Short sighted contempt of user experience and efficiency. The new Microsoft way and why we are no longer a Microsoft shop.

wow JFSSS. to the point. Unfortunately MS does not care.

I fully agree with all the posts that MS is absolutely deaf and dumb regarding how they write software for Mac and MS is obtuse to the obvious need for user friendly software, in particular, forcing consumers to use inferior, unwanted products like MS Outlook.

MS must improve Outlook by:

1. Guaranteeing the ease of migrating all of a users folders and files as the user has organized in their Legacy Outlook;
2. Not force consumers to use a product they have rejected;
3. Allowing users to easily return to Legacy while maintaining the original consumers organization of their email, folders, contacts, calendars, etc;
4. Allowing ease of Importing from the consumers Main Identity as MS once did so efficiently;
5. Allow the use of Rules.
6. Allow the Retrieval of Sent Email.

Anything less is inexcusable. Microsoft's Customer Care and Customer Service is the worst in the business. One should be able to make a phone call to a mutual-billion dollar company and receive instant in-person experienced technical support for free. The caps are for emphasis and not yelling: IF MICROSOFT DOES NOT MEET CONSUMERS NEEDS AS EXPRESSED ABOVE, THEN ALL APPLE USERS NEED TO ABANDON MICROSOFT OUTLOOK and use Apple Mail. MS Outlook has NO VALUE in its current "New Outlook" Form. For MS "New" means "Old and Neanderthal"

Yes this worked for me but try at your own risk. This is a Microsoft product after all.

The reason I don't like the new version is that it won't let Mac users all the filter for emails especially Categories. I use this all the time to organise which emails have been actioned but the new version won't let you select it to filter. This has been reporting as feedback into the black hole of Microsoft support.
