Trying to connect message when Saving in Excel 365

Actually, I have 2209 (15619.20070) in testing and it was working great until yesterday. The only thing that changes was that I applied some Windows Updates. 09-2022 September Roll Up feature update, .Net 4.8 update and a Security patch were the three updates that were applied throughout the day on Monday, and the problem reoccurred starting Tuesday morning.

Not sure if the updates have anything to do with it, or if something changed, but it definitely is a problem again. Probably going to roll back to 2206 build that was stable.

I tried the 2209 version you listed and it is still broken for me. Been trying every version I can find to no avail.

The fix worked for me, however, the next day, Office did an update and actually took me back to the most stable Office release which was 2208. So I went back and did the click to run fix again and applied the 2209 patch and turned off updates. It has been smooth sailing since with no issues. I have only tested on three PC's at this point, but I am slowly rolling it out to more machines.

I just updated to the Current Channel (Preview), Version 2209, Build 15629.20070 and am still getting the Trying to Connect issue when saving files to a network share.

I don't know if they fixed it and then broke it again or if I have to restart my computer to actually get the changes full applied.

There has been some progress on this issue, the fix is now in the Current Channel Preview release. I expect this fix will get rolled out to the Current Channel on October 11th and the Monthly Enterprise Channel on November 8th. It looks like the issue will be in the next release of the Semi-Annual Enterprise Channel unless things change...
