Delete Read Receipts using MFCMAPI

If you have hidden, unknown messages that won't send, it's most likely read receipts. They are stored as hidden messages at the root level of your mailbox.

There are two methods that can be used to delete them:

  1. Change the SMTP server for the account to a server you can access send. (Remember to change it back to the one you normally use for the account after they are sent.)
  2. Delete the hidden messages using MFCMAPI, OutlookSpy, or MDBVue. (MDBVue is out-dated and we recommend using MFCMAPI or OutlookSpy.)

The advantage of using MFCMAPI is that it does not install a program, the exe runs without making changes to your computer and it does not require you to close and restart Outlook.

If you prefer to use OutlookSpy, instructions are at Delete Stuck Read Receipts using OutlookSpy.

If you have a problem with a message that keeps sending over and over (recipient gets multiple copies) but its not in your Outbox, its usually caused by an antivirus scanner add-in scanning outgoing messages. If the message keeps sending after you disable email scanning and its not visible in the Outbox, you can look for it and delete it from the data store using the method here.

Use MFCMAPI to Delete Stuck Read Receipts

Download and run MFCMAPI. Use the 32-bit version with Outlook 2007 and earlier or Outlook 2010 32-bit and the 64-bit build with Outlook 2010 64-bit.

1. From the Session menu, choose Logon and Display Store table

Log on to default store

2. Next, go to MDB menu and Open Default Message store.

Open the Default message store

When a secondary account has its own message store and places the outgoing messages in its own Outbox, select that account and right click, choose Open Store.

Tip: you can right click on the account in the list and choose Open Store instead.

3. Right click on Root Container and choose Open Contents Table

Open the root container folder

4. In the Contents table, right click a read receipt and choose Abort Submit. Ok the dialogs.

Right click on the receipt

5. Right click again and choose Delete message. Ok the dialogs.
Delete the read receipt

Repeat steps 4 and 5 for each read receipt you need to delete.

Note: Outlook Connector (Live/Hotmail/MSN) accounts do not return read receipts and you will not have any "stuck" receipts with these accounts.

  • JIm Robertson

    My Outlook 2007 frequently stops sending messages that are in the outbox. Mostly it will clear once I stop and restart the application but shortly thereafter it stops again. I am using IMAP. I have disabled my Norton outbound email scanning.

    Can you help please.

  • beth

    I am having the same issue as Jim...is MFCMAPI still the answer for 2007?

  • ClaudioB

    Great job, I've had the same problem on a Windows7 PC with OL2010, there were 2 read receipts stuck: I've followed you steps carefully and they worked like a charm!!
    Thanks for your precision and accuracy !!

  • harry_techie

    Thank you for the detailed instructions, it helped me a lot, i was stuck with 1200 "Message Not Read" notifications, couldn't get rid of it until i followed this.

  • Lynda

    Unfortunately that turned out not to be my problem. My Outlook 2010 continues to send numerous emails that are not mine. Anything else I can try to eliminate these? Any help is appreciated.

  • Diane Poremsky

    What are the messages? It's pretty impossible for Outlook to be compromised - are copies of the sent messages in your sent folder? It's more likely your email account is compromised - immediately change the password on your account.

  • David Hicks

    Followed instructions precisely and MFCMAPI removed 3 of 4 'stuck items', the 4th a Read Receipt refuses to budge. So we are only a liitle further forward but still cannot use the Outlook. Do you have any advice on next step. Machine is runs Windows 7 64-bit with 32-bit Outlook.

    Grateful of any advice.

  • David Hicks

    Hi, I used the HARD DELETE option and the message cleared.

    Thanks your Tool worked a treat!

  • Tsvetelina

    Thank you! It worked for me.

    Error: Store does not support the IExchangeManageStore interface
    Code: MAPI_E_INTERFACE_NOT_SUPPORTED == 0x80004002
    Function lpMDB->QueryInterface( IID_IExchangeManageStore, (void **) &lpIManageStore)

    This is a copy of what happens when I try to do the fix for items stuck in my outlook outbox...of course I am puzzled??? This problem came out of nowhere and I haven't a clue how to get my outlook to send mail again....

  • Diane Poremsky

    What version of Outlook and what type of email account do you have? I can't ever repro it but i know it's not uncommon.

  • Whatever isn’t taken

    Same result that Larry Brooks gets. Outlook 2007, Windows 7 Home Premium.

  • Diane Poremsky

    I'll keep trying to repro the error - I know you two aren't the only ones who get that error, but I don't know the cause.
