Classic Outlook - Until when will it be supported & available for use?

I just downloaded the free version of eMClient to test for the future and it's actually fairly similar to Classic Outlook. I just set it up with an email I rarely use and was able to download my emails that I had saved as PST files as well as my contacts. Haven't figured out how to download my calendar in to it yet but other than that it's been pretty simple to use and modify to suit me. I am still using old Outlook as my main email program but I think that this could be a decent alternative. There is absolutely no way I will ever use the New Outlook, garbage is too nice of a term to refer to it! I'd like to be familiar with an alternative before it becomes the only choice and being able to download my old emails to a new program is very important to me.

Why is it when people at microsoft change the format on outlook they do it after they have had a lobotomy.???

the new version sucks. The features provide no improvements to the user. What Is MS attempting to do? It seems like you get one thing fixed and another whack a mole pops up. Now I have to look for another email system...anybody?

Wait for a bit. They always seem to release half a product but add to it over time.

In a couple of years it will be very different to the product at the point of release.

Teams, PowerBi, PowerApp, Flow were all the same.... hang in there.

I've just discovered that Icloud for Windows is not supported in new outlook. Very disappointing.

Whether Microsof listens or not but, the New outlook is ABSOULTELLY AWFUL. Im sure that they did Beata testing and also interviewing their customers right? uh no. Also, the Office 365 policy thats in place is JAMMING the new outlook down my throat WITHOUT an option to say no. BAD CHOICE! I do however have the option to flick the swtich back to classic but seriously Microsoft you ned to start listening to your customers and do a better job at informing your office 365 customers!
