Hi, I have an on prem Exchange 2013 and I need to set it up so that users can received large attachments.

This is the error I'm getting :





Searching on the net, seems to reveal I need to check a few things to increase and then restart the Information Store or the Transport Service.  I've done all three, restarted the two services, but it still has an issue with the incoming email.

This is the first thing I've checked:

1) All of my receive connectors are set properly, as in the MaxMessage size is large:


2) Transport Config is set to allow a large size:

This is where I thought the original problem was, since the bounce back message is saying the limit was 50MB.  50MB was the old value, and I've changed it to be an odd number, 111MB, and again, restarted the Transport and Information Store services, but made no difference.

3)The recipient's mail box is allowing for larger emails:



4)Using ECP, I navigate to the Message Size Restrictions for the account I'm sending to, and check on the override value I've custom Set, this matches the number in previous step:


5) My send connector is only 35MB but that shouldn't matter, since I'm receiving not sending:


So either I'm restarting the wrong services?
Maybe I need to wait longer?
Just seeing if I'm missing something obvious? Do the values need to be the same? or?? 

Any help would be appreciated.

Thank you
