Question

Outlook 2010 limits the size of attachment I can send, how can I make this bigger or unlimited?

Answer

To modify the default attachment limit size in Outlook 2010 follow these steps:

  1. Exit Outlook.
  2. Start Registry Editor.
  3. Locate and then select one of the following registry subkeys:

    HKEY_CURRENT_USERSoftwareMicrosoftOffice14.0OutlookPreferences
    HKEY_CURRENT_USERSoftwarePoliciesMicrosoftOffice14.0OutlookPreferences
    Note Manually create the path in the registry if it does not currently exist.

  4. Add the following registry data under this subkey:

    Value type: DWORD
    Value name: MaximumAttachmentSize
    Value data: An integer that specifies the total maximum allowable attachment size. For example, specify 30720 (Decimal) to configure a 30-MB limit.

      Notes

    • Specify a value of zero (0) if you want to configure no limit for attachments.
    • Specify a value that is less than 20 MB if you want to configure a limit that is less than the default 20 MB.
  5. Exit Registry Editor
  6. Start Outlook.
