While opening an existing/ new InfoPath form, it is getting opened in the Read Only Mode.

Scenario:

 

I've published an InfoPath form (Filler Form) on a SharePoint library. While opening an existing/ new form, it is getting opened in the Read Only Mode.

 

Cause and Solution:

 

There could be multiple reasons for this. I've came across two scenario.

 

  1. A new form/ existing forms are getting opened in Read Only. I looked at the procmon trace and found below trace,

 

12:25:09.9318393 AM TMBMSRV.exe 5688 CloseFile C:\Users\Test\AppData\Roaming\Microsoft\Office\Recent\Sharepoint - 2016-07-12 - Test.xml on sharepoint.Test.org.url SUCCESS

 

12:25:09.9320745 AM INFOPATH.EXE 12384 QueryAttributeTagFile C:\Users\Test\AppData\Roaming\Microsoft\Office\Recent\Sharepoint - 2016-07-12 - Test.xml on sharepoint.Test.org.url SUCCESS Attributes: ANCI, ReparseTag: 0x0

 

Which means TMBMSRV.exe (Trend Micro Antivirus), is accessing the XML before InfoPath. TMBMSRV.exe was a client side antivirus and removing this antivirus, fixed this issue.

 

 

  1. An existing form is getting opened in Read Only but new one works fine.

 

The issue was only on Windows 7 machine and we found Web Client has a limitation of 50 MB. This limit is by default and could be modified, if needed from “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters\FileSizeLimitInBytes”.
