Using Classic Outlook on Windows for personal email, calendar, and contact management
The service team has resolved the incident. If it's not fixed it should be soon. Are you still reproducing the issue?
It is still happening for me - just jumps out of the search bar when I try and search my hotmail account in Outlook 24 - but is fine for Gmail and Sky accounts in there?? Using the suggested workaround of searching in the sky or gmail mailbox using the All Mailboxes option
