Hi MA,
Please do these three things - I assume it is not a Microsoft exchange account.
- Delete any unknown or suspicious contacts from Outlook
- Open Outlook → Go to People / Contacts
- Review all saved contacts carefully
- Remove any entries you don’t recognize or didn’t add yourself
- Clear all pending or suspicious tasks via Microsoft To Do
- Open Microsoft To Do (web or app)
- Check all lists including Tasks, Planned, Flagged Email
- Delete any unfamiliar or automatically created tasks
-
- Check and remove any malicious or unwanted Outlook rules
-
- In Outlook, go to Settings (⚙️) → Mail → Rules
- Look for rules that:
- Automatically delete emails
- Move emails to Junk/Spam/Deleted Items
- Forward emails to unknown addresses
- Delete any suspicious rules immediately
- Save changes and restart Outlook
- Also verify Junk Email settings
- Go to Settings → Mail → Junk email
- Check blocked/safe senders list
- Remove anything suspicious or unfamiliar
- Optional but recommended
- Change your account password
- Enable 2-step verification for added security
I hope this information helps. If you have any more questions, don't hesitate to reach out.
Otherwise, please take a moment to rate the answer. Wishing you good luck!
