I’ve set and confirmed no limits are set on attachment sizes and I’ve been able to send out attachments over 8MB no problem on my PC and in Outlook, but I have one Mac user using Web Access getting “The following files weren’t attached because the exceed the maximum size limit for attachments (5MB): filename.ext”
This didn’t make any sense. But luckily another user posted about this same problem and had the solution:
Even though the limit was set as unlimited, the outlook web client for this user saw it as not set so it applied a default limit of 5MB. Crazy. This command fixed it..and a restart of IS service:
set-transportconfig -maxreceivesize:1024MB -maxsendsize:1024MB
