Microsoft Outlook: Attachment exceeds allowable limit

You maybe get a warning in Outlook that the allowable attachment size is exceeded though you have defined a higher value in Kerio Connect as the attachment you wish to send.

The problem is in Outlook 2010 itself, not a Kerio Outlook Connector Offline Edition (KOFF) specific issue. You find a solution in the following Microsoft article in the section "Resolution > Internet email account" You can either download the Microsoft Fixit Tool or tweak your registry.


The problem is still present in Outlook 2013!

Details how to fix it can be found in Microsoft Knowledge base:
