Hi!
Welcome to Microsoft Q&A forum.
This clearly show two separate but related Outlook/Hotmail issues:
- “Couldn't send this message: Bridge”
- “Your message wasn’t sent because there’s a daily limit for how many messages can be sent”
Let's check it one by one.
- Go to https://outlook.live.com, do a test email to yourself.
This bypasses the “Bridge” service and often works even when the app is rate-limited.
- Confirm You Haven’t Hit the Limit
Go to https://account.microsoft.com/security look for any alerts labeled “Sending limit reached.”
Note: After doing a test (1 email only) email stop already. Since we're trying to identify if it reached the limit of sending out emails each one ca extend the block (if you really hit the limit)
