Hello Intune Administrators !!
Those who are new to Intune Win32 app deployment then GRS will be confusing word for you. Wait ! dont worry. I will explain basic of GRS. So, GRS is acronym for Global Retry Schedule. You can see below in IntuneManagementExtension.log during Win32 app troubleshooting.
[Win32App] Tried in last 24 hours, No need to exec. skip execution 3 IntuneManagementExtension 9/1/2020 7:38:07 AM 26 (0x001A)
[Win32App] app AdobeReader with id 54b889093-9a31-8549-fgd2-27cb141a5g789 is still in GRS. GRS start time is 8/31/2020 9:16:35 AM IntuneManagementExtension 9/1/2020 7:38:07 AM 26 (0x001A)
According to Intune Win32 app deployment, when a Win32 application deployment tried in a particular date and time then next retry will happen exactly after 24 hours.
In above event, Win32 app "Adobe Reader" retry was skipped execution because during check, it was found that retry was happened < 24 hours and therefore IME (Intune Management Extension for Win32 app deployment) skipped the execution.
Hope this post is useful. If you have any query, feel free to comment.
