I don't write code, but I'm posting a question here because I don't know where else to turn. Why do some Outlook emails open with a deeplink window instead of just showing the full-page email like it's supposed to? I have no mobile devices connected to this acct. and I've sent dozens of emails to Outlook Support and Microsoft which were useless. I've also tried to find help in other forums, but still have no answers, as if deeplink is a big secret.
The email URL usually starts with https://outlook.live.com/mail/0/deeplink?version . . . . etc. and opens in a new, smaller window. I just want to know what's causing this and how to stop it or turn it off.
I've tried all kinds of "fixes" as instructed by Outlook Support and none solved the problem. I don't expect a lengthy discussion, but if anybody can tell me what to do, I'd really appreciate it.
