This fix worked - thank you so much for whoever shared this.

 

open cmd, run:

cd \Program Files\Common Files\microsoft shared\ClickToRun

then enter:

officec2rclient.exe /update user updatetoversion=16.0.6366.2062

 

Good luck

      This worked for me yesterday. Although it did take my Office back many versions. At least I can check my mail.

       

      open cmd, run:

      cd \Program Files\Common Files\microsoft shared\ClickToRun

      then enter:

      officec2rclient.exe /update user updatetoversion=16.0.6366.2062

        Alex_LCTried that and it says I have the latest version, so I have to go into the task manager and shut outlook down then restart the program for it to run  what bs.

    Frank_Petrus That version would depend on which O365 Update Channel you are on though. 

    I'm having the issue with Current Channel: Version 2006 (Build 13001.20384). 

     

    So I would need to go back to Version 2005 (Build 12827.20336)

     

    The 16.0.6366.2062 listed in that 'fix' is an Office Insider build from 2016... Probably don't want to go all the way back there 🙂
