    Hi @Janis Gustaps ,

    Welcome to our forum!

    Have you done any specific operation before the issue occurred?
    And for the freezing randomly you mentioned, does the issue occur on the client of random users?

    As I know, the issue occurs when Office is contacting a remote location(such as a printer, an email server), if it's your case, please refer to this article for troubleshooting: Why am I getting the message "Contacting the server for information"?

    If this doesn't work, according to my research, I found that in some posts users mentioned that HTTP images downloading when opening or forwarding e-mail would cause this problem. It's suggested that you could try to edit the registry as follows:

    1. Select Start, select Run, type regedit in the Open box, and then select OK;
    2. Locate and then select the registry subkey: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common;
    3. Right Click on Common>New> DWORD (32-bit)> enter BlockHTTPImages and set the value to 1;
    4. Restart the computer and start Outlook to check if there're any differences.
      (It should be noted that if you modify the registry by mistake, serious problems may occur. Please back up the registry before operation.)

    Hope the above help!

    There are many possible reasons for Outlook freezing randomly.

    1. If the user ignoring install the latest updates
    2. Broken Outlook data files
    3. If the profile becomes corrupt.

    You can fix this problem by arranging a few things.

    1. Open your Outlook in a secure mode.
    2. Shut down Outlook carefully.
    3. You can repair your Outlook data files.

    These are some manual tasks that can help to resolve Microsoft Outlook's stop responding problem.

    This is one of the basic problems faced by every Outlook user. Last week I received a Mail from an unknown source. Somehow I opened the mail and Bang, my Outlook Freeze. No option is working at that time.

    I tried every possible solution to open it. Googled every possible solution to find the proper way to resolve the problem, then I found one link which help me out:


    I hope it helps.
