Exchange / WAF - OWA, ActiveSync 1MB File Limit - SFOS 19 GA

Question

I'm getting following error in WAF-log: 
 ModSecurity: Request body no files data length is larger than the configured limit (1048576) 
 Is there a new switch in gui or command line to increase 1 MB limit in V19? There were forum posts some years and some month ago that indicated there would be a solution in future? 
 Anything i can do except contacting support? KB-article? 
 Are these command for advanced shell still usable in V19? still only temporary fix? 
 
 ## 1. find correct ID:
psql -U nobody -d corporate -c "select name,id,sec_request_body_no_files_limit from tblwafsecurityprofile;"

## 2. Update limit with previously selected ID:
psql -U nobody -d corporate -c "update tblwafsecurityprofile set sec_request_body_no_files_limit='52428800' where id ='7';"

## 3. Check successfully updated value for sec_request_body_no_files_limit:
psql -U nobody -d corporate -c "select name,id,sec_request_body_no_files_limit from tblwafsecurityprofile;"

## 4. Update config:
opcode waf_reconfig -t json -b '{"Entity": "waf_advanced_config", "Event": "UPDATE"}' -ds nosync

Hello FFin , You can refer the following commands below, before executing ensure to take a backup of the existing config: 
 psql -U nobody -d corporate -c "select id, name, comment, sec_request_body_no_files_limit from tblwafsecurityprofile;" 
 id | name | comment | sec_request_body_no_files_limit ----+---------------------------+---------------------------+--------------------------------- 4 | Microsoft Lync | Microsoft Lync | 1048576 5 | Microsoft RDG 2008 | Microsoft RDG 2008 | 1048576 6 | Microsoft RD Web 2008 | Microsoft RD Web 2008 | 1048576 3 | Exchange Outlook Anywhere | Exchange Outlook Anywhere | 1048576 1 | Exchange AutoDiscover | Exchange AutoDiscover | 1048576 2 | Exchange General | Exchange General | 1048576 7 | Exchange General (neu) | Exchange General | 1048576 (7 rows) 
 You can run the following to increase to 52 MB for example ( for 52MB value will be 5,242,880 ) 
 Support can help you update the size from 1 to your desire value, an example is shown above, with that reference value you can contact support. ==========================================================
