Update error code 30088-27 Office 2021 what to do to get corrected????

I will gladly join it, and I am sure some of our customers will too.

Yes. Now I am wondering, though, how many users have NO IDEA this is even an issue. Is that right? I mean, there must be thousands (maybe tens or hundreds of thousands) who either don't pay attention to updates or just assume they're getting done in the background automatically (and maybe don't even know how to manually check)??

I am a simple user not a Computer graduate. I do not go in an change or back date software to make it work.

I NEED MS TO CORRECT THEIR CONNECTION SO THAT THE THEIR UPDATES WILL DOWNLOAD.

THAT IS THEIR JOB NOT MINE!!!!!!!

It is just incredible that MS can't understand plain English. As you know, I have been working with a 365 Support agent since the very beginning and hammering him because of his illogical replies. As it is Friday, I guess you need a good laugh as they keep trying to blame everything except themselves.

-------------My Reply---------------

So here we go again …. Looking to blame settings or network issues. I am sorry, but this is a known issue, well documented in communities threads and I am not going to invest (not to say lose) my time on this.

A machine that was working perfectly and updates were flowing till last month, it is now not updating Office and you are still looking to blame ANYHITNG but yourselves.

I will share your post with the community so they can laugh too.

MS 365 update error 30088-27 consistantly now for Outlook, Word, Excel, likely starting after the upgrade to Ver 2406 Build 16.0.17726.20078. Have tried the repairs, and then deleted/reinstalled MS 365 ... still this error. Have tried the two netsh commands noted here ... still this error. Platform is Win11 23H2 at the latest maint level.

Same here on 2019. Everything else running OK.
