Guide Overview

First, open the Start Menu and type regedit in the Run box:

Next, open the following link:

HKEY_CURRENT_USERSoftwareMicrosoftOffice14.0OutlookPreferences

Right-click the empty window area to the right of the Preferences key and select New> DWORD (32-bit) Value:

Name the newly created key MaximumAttachmentSize, change the value again through the Modify section. The value we enter in the Value box will become the maximum capacity allowed for Outlook attachments, the unit calculated here is kilobite. For example:

0: unlimited 1048576: 1 Gigabyte 102400: 100 Megabytes 51200: 50 Megabytes 1024: 1 megabyte

Very simple and easy. But consider the actual use and speed of Internet connection, and not all ISPs support such large attachments. Some common ISP limitations:

Gmail: up to 25 MB Google Apps: 20 MB or 50 MB for Premier accounts AOL Mail: 25 MB Live Mail: 50 MB

Good luck!
