Why is Outlook Not Receiving Emails from Specific Sender?
There are various reasons for not receiving new emails in Outlook from a particular sender. Some of them are mentioned here.
| Possible Cause | What Happens |
|---|---|

| Apply Junk Filter | Emails move to Spam/Junk folder |
| Inbox Rules | Messages get deleted or redirected |
| Antivirus Filtering | Security software blocks emails |
| Mailbox Storage Full | Outlook stops receiving new mail |
| Outlook Profile Issue | Profile corruption affects syncing |
| Corrupted Outlook Data File | Sync issues prevent email delivery |
Here are the different situations that cause this Outlook error. Now let’s talk about the different methods that solve it.
Top Fixes to Solve Outlook Not Receiving Emails from Specific Sender Error
1. Check the Junk Email Folder
Sometimes Outlook mistakenly flags the emails as spam, thus moving it to the junk folder. Check it if that is the case.
- Open the Junk Email folder
- Search for the sender’s email address
- Right-click the email
- Select Not Junk
If the email appears there repeatedly, add the sender to the Safe Senders list.
2. Remove the Sender from the Blocked List
If you accidentally add the sender to the block list, then it can be the reason for this error. Check the list, and if the email address is in it, then remove it.
File → Options → Mail → Junk Email Options → Blocked Senders
If the sender’s address appears there, then remove it from it. After that, restart Outlook.
3. Review Outlook Rules
In Outlook, there is a feature that allows you to set rules for sending and receiving emails. If there are any incorrect rules, it will silently move emails away from your inbox. Check out if there are any such rules.
- Go to File → Manage Rules & Alerts and Check out if there are any such rules.
- Rules that move emails to another folder
- Auto-delete rules
- Category-based filtering
- Forwarding rules
Disable suspicious rules temporarily and test again.
4. Add the Sender to Safe Senders
This tells Outlook to always trust emails from that sender.
- Open Junk Email Options
- Go to Safe Senders
- Click Add
- Enter the sender’s email address
- Save changes
This prevents Outlook from treating future emails as spam.
5. Check the “Other” Tab in Focused Inbox
Each mailbox focuses Inbox sometimes and moves the unrelated emails to another folder. First search for missing emails in other folders. If found:
Right-click the email >> Choose Always Move to Focused
6. Free Up Mailbox Space
A full mailbox can stop new emails from arriving. Therefore, freeing up the space can solve the “Outlook Not Receiving Emails from Specific Sender” issue. Thus you need to do is;
- Empty Deleted Items
- Remove old attachments
- Clear Junk Email folder
- Archive unnecessary emails
After cleanup, restart Outlook.
7. Repair Outlook Data File
If your OST file becomes corrupted, Outlook may fail to sync emails properly. First, fix corrupt OST file and create a healthy data file. For that, use SCANPST.exe if you are using the new version of Outlook. Follow These Steps
- Close Outlook, and after that, locate SCANPST.exe
- Select your OST file and start the scan
- Repair detected errors
- Once repaired, reopen Outlook and check for missing emails.
8. Create a New Outlook Profile
A damaged Outlook profile can cause selective email delivery issues. Create a new profile and try to resolve the issue.
- Open the Control Panel and Select Mail
- Click Show Profiles >> Choose Add
- Create a new profile
- Configure your email account
- Set it as the default
Launch Outlook using the new profile and test email delivery. Even if the issue is still there, try these additional tips;
