Attachment size limit in Exchange 2013 - CANNOT figure out how to increase it more than 5MB


  • Hi everyone,

    Im using Exchange 2013 and my users are complaining that they cannot send an email with an attachment over 5MB. I checked to make sure that my send/receive message size limits were OK and they are both set to unlimited. The message sizes are fine, its just large attachments.

    I tried to use a rule in the EM but the rules don't work, powershell seems like the only way.

    Does anyone know the powershell command I should use to increase the attachment size limit to say 20MB?? Ive looked all over, tried it myself and I cannot get the command right...any help would be SO APPRECIATED!!!
