Configuring preferences and options in Outlook.com
Hi MALATESTA Bree [Amaroo Primary School]
From your description, I understand how annoying it is when you try to remove a contact from your Blocked senders list but Outlook.com just shows "Something went wrong" instead of saving.
Have you tried the steps in the Q&A Assist reply yet? And are you using a personal Outlook.com mailbox (ends with @outlook.com/@hotmail.com) or a work/school mailbox in Outlook on the web?
Meanwhile, please try the following:
1, Add the sender to Safe senders (so mail won’t go to Junk)
- Sign in to Outlook on the web
- Go to Settings > Mail > Junk email, add the sender under Safe senders and domains, then Save.
2, Refresh the web session
To force a fresh session: please sign out of Outlook.com, close the browser, reopen it, sign back in, then try saving the change again.
Please let me know if the Save error continues so I can guide you further. Thank you for your time and understanding.
