Blocked senders and domains list has disappeared, Outlook now not saving blocked list

Over the years, I have consistently tried to block unwanted senders to reduce phishing scams coming into my inbox. In recent weeks, the list of hundreds of blocked sites seem to have disappeared without me doing anything to delete them. When I now block senders, they appear on the list but when I log into Outlook on the web on another occasion, the list is blank again of blocked senders and it looks like my attempt to block sites is not saving.

    Same issue here too. Probably the last straw for me; will delete Outlook.

    Same issue here. I'm starting to assume it might have happened to everyone using Outlook.com. Like others here, I had hundreds of blocked emails and domains in that list that I've been building up for years.

    I've noticed the same behaviour as the main topic mentions when attempting to add new entries. That is, it looks like they are added at first, but once you leave the screen and return, the new entry is gone as well. That actually gives me a little bit of hope that maybe this isn't a case of Microsoft accidentally deleting all our blocked sender lists, and may actually just be a temporary bug with loading them. One can only hope.

    Another thing that would have helped here is some way to export and import the block list. The format could just be a plain text file with one email/domain per line. I might have backed them up except no option to export the list was ever provided.

    I have the same problem. I find it shameful that you limit yourselves to answering with ready-made answers, this is a BUG that should have High priority and you are doing absolutely nothing.

    First, you should reestablish the lists of blocked senders that we all had, why else do you make backup copies? Then, disable whatever deleted them. But it is easier to look the other way.

    I had some users report this as well. I went to Outlook online and the "new" version and mine were gone also. If you open the classic version, your list should still be there, that is where I found mine. The users were also able to view the list from classic as well. To view, on home tab select the drop down by junk, and choose junk e-mail options. There will be a blocked sender tab. As for why they disappeared in the two other versions, I don't have an answer for that yet.

    How are you still managing to get to Classic view, Justen? I know there used to be a special URL for it ( https://outlook.live.com/owa/?path=/classic ), but that just opens the modern view for me these days.

    Or are you talking about the Windows app version?
