"my outlook" doesn't seem to be MS Outlook (the program in the MS Office suite), but the website outlook.com that you visit in your browser. That's correct?

Things to try:
1. Another browser on this PC/laptop.
2. Another PC/laptop/tablet/phine on the same location as you do this.
3. Another device on another location.

#3 should work. And #1 or #2?
