Outlook 365 crashing on Server 2016

Question

Three terminal servers all with the same error today, all using Microsoft Office 365 and Server 2016:

“The required file react-native-win32.dll cannot be found in your path. Install Microsoft Outlook again.”

“Microsoft Outlook has stopped working”

“A problem caused the program to stop working correctly. Please close the program.”

A quick repair, a full repair, even uninstalling, rebooting and installing again didn’t fix the issue. On one server I uninstalled all of the recent security patches and rebooted, but no change.

I rolled it back to 5th December 2024 using the command below and it seems to be stable again:

cd %programfiles%\Common Files\Microsoft Shared\ClickToRun
officec2rclient.exe /update user updatetoversion=16.0.18227.20152

Answer 1

Thank you for this info.

Was able to get our Office users back up and running this morning.

Answer 2

Outstanding ... worked perfectly.

Will freeze all updates (inc Office) via sconfig on all VMs till more info.

Answer 3

Same issue here, Server 2016 as an RDS host ; Office apps all crashing. Will try the rollback as suggested above.

Answer 4

Exactly the same circumstances here. Server 2016 as remote desktop hosts and Office 365 : all Office apps crash rect-native-win32.dll after the update KB5048671.
