An administrator reported that some of his users had problems with messages hanging in the Outbox and pressing Send & Receive crashed Outlook:

"Some emails sit in the Outbox and won't send. I've checked the settings and can't find anything. It's not affecting every message, just some. If we try a "Send All" Outlook crashes. After a restart, the messages will send. "

Problems with send and receive are almost always caused by corrupt send/receive settings. Go to the roaming app data folder, browse to \Microsoft\Outlook and delete or rename the SRS file for your profile then restart Outlook.

Windows 7 or Windows 8

The SRS file is located at C:\Users\username\AppData\Roaming\Microsoft\Outlook. You can access it by typing or pasting the following line into the address bar of Windows Explorer and press enter:


Windows XP or Windows 2000

Look for the SRS file at C:\Documents and Settings\username\Application Data\Microsoft\Outlook. Type or paste the following line into the address bar of Windows Explorer and press enter to access it:

%USERPROFILE%\Application Data\Microsoft\Outlook

A corrupt SRS file can also cause Outlook to crash when you expand the Tools menu in Outlook 2007 and older. (As will a corrupt outcmd.dat file.)

    I find nothing of help here. For a week now I have not been able to send or receive emails. A company I pay to come in and fix this has said they can not and a thing keeps popping up that says server user name ( and asks for a password. it has been reset to and says dave this password list. This can be deleted but constantly returns again in the middle of the page and the mail will not come in or or go out. I have also contacted AT&T but they say it is not their problem,. I don't kn ow where to go but you and I need to talk to some one live to gt it straightened out. HELP

      I found out our issue with a user that was having crash issues on multiple machines. The issue was in the icloud calendar subscriptions. There was one calender that was setup in their account on the server that I guess no longer existed. Instead of skipping when trying to sync the calendar it crashes. I asked about it and they said they don't even remember subscribing to that calendar so I deleted it on the server side and no more crashing.

      What exactly is the problem? What type of email account do you have configured in Outlook?
      does it work if you restart outlook in Safe mode?

    I'm having the same issues, have been for months. I paid a service to help me, they told me my laptop was old. I have a brand new laptop and SURPRISE my desktop outlook continues to crash when I try to send emails. Doesn't even save the message so I have to re-type all over again. I tried to log in to Microsoft Support and it won't accept my username and password. Beyond frustrated. As a small business owner I do not have time for this to keep happening. AT least 6 months here... yeah, do not buy.

    • Diane Poremsky says

      Does it crash in Safe mode? Does it crash when you are composing the message or after you hit Send?

    • Diane Poremsky says

      That often means a problem with the SRS file. What version of Outlook do you use?

  3. Vanesss says

    Most recent download off Microsoft 365 so it is up to date. Crashes on my other computer running 2010 too, a fully installed version.

    • Diane Poremsky says

      if it crashes on two systems, something is seriously wrong. The files that could cause a crash are not normally shared between installations. Does it happen in Safe mode on both computers?

    Problem was with the Internet Calendars in Account Settings. I had an unknown calendar. I removed it and it now works fine!

    problem solved!

    1- close outlook.
    2- lookup for .srs at C:\Users\username\AppData\Roaming\Microsoft\Outlook
    3- delete that file (it wont affect anything, just for resetting the send/receive process)
    4- open outlook, quickly cancel the send/receive process (right click at the bottm right > cancel send/receive)
    5- send/receive tab > download inbox header
    6- right click on one of the inbox header > mark to download
    7- send/receive tab > process mark header
    8- repeat step 6&7 until all inbox header is completely downloaded.
    9- click on send/receive

    hopefully it helps!

    ps. i also uncheck all addin. and repair the micr office before i did this. sorry for my english!

      Downloading headers shouldn't be necessary - as soon as you delete SRS file, it should work ok. (Plus not all account types and versions of Outlook support headers-only).

  6. eva says

    after i delete the .srs and click on send/receive. it crashed.
    even when i download header only >> send/receive, it stopped working (when downloading the inbox).
    then i tried step 5-9, it works fine.
