Trying to connect message when Saving in Excel 365

I just wanted to report this is an issue for the Semi-Annual Business Channel people, like my company.  My Office just updated from 2202 to 2208, and right away I noticed this issue happening saving attachments in Outlook and saving files in Excel  (oddly did not happen in Word).  I found this thread after searching about the problem...  I cannot believe an issue that was supposed to be fixed, is back for a 'new' update.  I realize 2208 is 'old' but the point of semi-annual business channel is to take feature updates at a more measured pace and let everyone else deal with stuff like this :(

For anyone interested in this, we've had a response logging this through our Microsoft Premier Support agreement.

I've bene advised that this is fixed in the Beta Channel release 2211. Not had a chance to validate this as we are running the Monthly Enterprise Channel (fix ETA Jan 23, Current Channel fix ETA Dec).

"There is a workaround that you can do" lol...

What is MS's award for finding the workaround?

I found this fix as well earlier today before checking my email. It worked fine. I went and rolled back to the last build of 2205 and it worked out so far with two test machines. going to roll it wide until a version fix occurs. I can tell you that most current build has not fixed the issue yet.

I found this way to roll back Microsoft Office 365 to a previous version.

Open Windows Command Prompt as Administrator, run the commands:

cd C:\Program Files\Common Files\Microsoft Shared\ClickToRun

officec2rclient.exe /update user updatetoversion=16.0.XXXX.XXXX

The version Current Channel 16.0.15225.20288(2022 June 14) worked for me.

You can find the Update history for Microsoft 365 Apps here:

I have Automatic Updates disabled until now.

For everyone,

Our organization have opened an official case to Microsoft about this situation.

Office Logs has been sent to Microsoft.

Don't know yet if it will be corrected, but I will keep information up to date in this post.

Also, the problem only occurs in Outlook and Excel when "Save as" tries to access "Documents" that has been redirected.

It does not seems to happen with Word and PowerPoint.

It does not happens with a user chose to open a document and access "Documents".

Instead of rolling back to an older Office 365 version on all workstations, by deploying a script or a package (in reference to AlexRib_sup suggestion), I believe that disabling by Group policies the service WebClient (as suggested by NaftaliGross) is simpler and easier to undo (by just delete the GPO) when Microsoft will publish a new version that corrects the problem.

Effectively, when disabled, the problem does not seems to happens.

But we haven't test yet impacts on shared cloud files (Teams files, sharepoint files, ...).
