Hello @Mansoor Anwer

Welcome to the Microsoft Q&A Community! 

Thank you for reaching out. I understand you’re not receiving emails from one specific client, and I’m here to help you get this resolved. 

Please follow a few checks and solutions below: 

1. Check All Folders 

Sometimes messages from a single sender get auto‑routed. Please search your mailbox for the sender’s email address and review these folders: 

• Junk Email 
• Deleted Items 
• Archive 
• Other (if Focused Inbox is enabled) 

If you find any emails from the client, please move them back to your Inbox and mark them as Not Junk. 

2. Review Junk Email Settings 

The sender or their domain may have been added to your blocked list by mistake. 

Go to Settings > Mail > Junk email and: 

• Remove the sender/domain from Blocked senders 
• Add them to Safe senders 

For reference: Add recipients to the Safe Senders List in Outlook - Microsoft Support 

3. Check Inbox Rules / Sweep Rules 

A rule may be moving or deleting their emails. 

Please go to Settings > Mail > Rules and disable any rules that: 

• Move messages 
• Delete messages  
• Redirect/forward messages 
• Filter based on keywords or sender 

4. Turn Off Focused Inbox (Temporary Step) 

Please turn off Focused Inbox under: Settings > Mail > Layout > Focused Inbox > Off 

This ensures the message isn’t being sorted into “Other.” 

5. Check Mailbox Storage 

If your mailbox is full or nearly full, new messages may fail to arrive. Please delete unneeded large emails and empty Deleted Items. 

If the issue continues, ask your client to resend a plain text message without attachments or links.  Sometimes emails with certain attachments or formatting get filtered automatically. 

If you’ve completed the steps above and still aren’t receiving messages from the client, please let me know and I’ll be happy to assist further.

If you are not receiving emails from only one client while receiving emails from others, there could be several reasons for this issue. Here are some steps you can take to troubleshoot:

1. Check Spam or Junk Folder: Sometimes, emails from specific senders can end up in the spam or junk folder. Make sure to check these folders to see if the emails are being filtered there.
2. Review Email Rules: It's possible that there is a rule set up in your Outlook that is diverting emails from this specific client. Check your rules to ensure that none are affecting the delivery of emails from this client.
3. Whitelist the Sender: If the emails are being blocked or filtered, consider adding the sender's email address to your safe sender list to ensure their emails are delivered to your inbox.
4. Check Email Client Settings: If you are using an email client (like Outlook), ensure that there are no settings that might be preventing emails from this client from being received.
5. Contact the Sender: Ask the client to check if their emails are being sent successfully and if there are any bounce-back messages. They might need to check their own email settings or contact their email provider.
6. Use Outlook on the Web: Log in to Outlook on the web to see if the emails are appearing there. If they are, the issue might be with your email client settings rather than the email account itself.

If these steps do not resolve the issue, consider running the Microsoft Support and Recovery Assistant, which can help identify and fix issues related to Outlook and email delivery.
