I am an independent journalist; using my usual MS 365/outlook, sending the same email article to some 120 publishers globally. I try to do them pasted into my emails one at a time. But after sending only 2 or 3, MS blocks me saying “unusual activity” as if I’m spamming. Then I cannot get back into that email account. MS keeps suggesting “too much activity” (after only 2 or 3?!) and “try again tomorrow.” Next day still blocked no matter how I follow MS’s usual unblocking procedures, still nothing. I never had this problem with a previous MS email on office/outlook.
Getting annoyed with modern MS the last few years such as Word, which I use all the time. I found Windows 2000 Pro/Word Pro the best and infinitely configurable and I may go back to it.
What to do other than use another non-MS system and provider?
