What is EOWP.22.2.49.0.EXE and why is it opened from office files?

Question

After running Microsoft office 365 online repair in our environment:

last tuesday night our security software (sentinel one and Rapid 7) are detecting suspicious activity from word and excel. They see that word and excel where opening a file called EOWP.22.2.49.0.EXE This is on existing files, so not any malicious attachments or anything.

The exact location is: \Device\HarddiskVolume4\Users%Username%\AppData\Local\Temp\18\eowp.22.2.49.0.exe

Could anyone tell me what EOWP.22.2.49.0.EXE is?

Here is some diagnostics from virustotal.com on the file: Here is some diagnostics from virustotal.com on the file: https://www.virustotal.com/gui/file/fdffdd1f1b3839a1cfdd66dc05d1c382e80e3a874ec32fae2a15e6b332657fb0
