Go back to old version of outlook.

If you mean the Beta version of Outlook.com there should be a slider switch in the upper right when logged into Outlook.com.

I have the same issue. My account seems to have switched from classic view to Beta without my doing anything. I do not see any slider anywhere to revert to the classic view.

I DO NOT like the new version of Outlook and want to go back to the format I am used to!!!

I DO NOT have a "toggle switch" visible on the top right — or anywhere else — of my screen.

I am using a MacBook, OS10   "High Sierra" Version 10.13.3    Is this a problem??   I USED to see the Toggle switch up top but I never, ever voluntarily touched that switch.  Now it seems i have been switched without my knowledge and certainly without signing up for or agreeing to any such change.  I can't use my email in this version.  Would MS prefer to start losing customers rather than allowing them to continue with a product they liked ??

Same here, annoyed very much.  More annoyed that no one from MS tech support have come forward. Previously when I tested the beta version twice, months apart there were many issues which I wrote about the issues I am having, on the beta versions. So many users were annoyed and no solutions were offered.  On top of that a few weeks ago I lost many thousands of emails which I needed to keep. Found out that others have too.

Specially annoyed with email trails result of replies from others and me. That is all messed up can't seem to work out what is happening.

This has made me think of voting with my feet by leaving if no one resolves this in a few days time.  PS After being with them since the day Hotmail started before MS buying them off.

I think they will take notice if enough of us threaten to leave.

Lets see I just want MS to take notice of these forums.

Real Microsoft employees, rarely, if ever visit these forums so no one from the Outlook.com team is going to take notice. Leave your suggestion in the feedback mechanism that is available in the ? menu when logged into Outlook.com. They do read those.
