Hello experts,

We have an Exchange 2013 server. All users are joint to the domain, except one user (Windows 8.1) which is in a Workgroup, and using Outlook 2013 with IMAP protocol. 

This particular user is having a problem. When he send's any email from Outlook and requests a read receipt, after that he keeps getting hundreds of read receipts in his inbox. I have tried disabling (for temporarily) the Windows server 2012 firewall,  but still having the same issue. 

Is this a known bug in Outlook 2013 with Exchange 2013? Any help troubleshooting this?

Hi,

According to your description, I understand that IMPA account get hundreds of read receipts while he requests a read receipt.
If I misunderstand you concern, please do not hesitate to let me know.

Whether are all account or some special user experience this question? Please do a test in external with IMAP account to double confirm.
How about the Request a Delivery Receipt?

Also, please run message tracking log to get more details about message mail flow:

Get-MessageTrackingLog Server mailbox server Sender a@abc.com Recipient b@abc.com MessageSubject Read: message subject | Select Timestamp, ClientHostname,ServerHostname,Source,EventID,Recipients,RecipientStatus,Sender | ConvertTo-Html > C:\Test\Test.xml
