Office 2016 Hangs When doing a Save-As

Could you include the version because different users on different release channels have different versions on different days. Such is life with O365 ;-) I'm using Version 1901, Build 11231.20080 and haven't experienced this issue.

Addendum : just updated to 1901 / 11231.20120

Does this happen with all files? Or only specific files?

Office 2016 1808 (Build 10730.20264)

Win 10 Ver 1803 (OS Build 17134.523)

I've even forced a PC to install 1812 (Build 11126.20266) with no success

This issue happens with any Office Doc... Even happens with a blank doc saved to the desktop

Oh, and it's all users. I just saw that.

Sure sounds like something that might be version specific. Hm...

Are you blocking access to the internet or hiding behind a proxy?
Recent versions of Office are geared up for Office 365 etc. and will try to connect to stuff like OneDrive every time you try to save as. if it's being blocked it will hang until the attempt times out.

nothing is being blocked... We all have OneDrive and SharePoint available as a save-as location. I should mention this issue does not happen on my Macs but the save as process with a mac is entirely different.

A couple of suggestions --

This one is from a colleague: I'd suggest that they disconnect from the network, disable antivirus/antimalware and also anything that's doing auto-backups or synching to see if that has an effect.  Not a solution but it might point the BlameFinger in the right direction.

This one is from a contact at Microsoft: Please have the users send a frown when this occurs. (I know it seems like a blowoff suggestion, and I know it doesn't help your immediate situation, but I can tell you from experience that this is the best way to get bugs and issues in front of the people who can research and fix them.)

the plot thickens... my users are reporting lost data over the past week because Office Apps are not alerting them someone is working in a file when opening it. They save their changes which get overwritten when the person that had the file open when they opened it saves the file.

I've got cases open with Office 365 Support but they don't seem to have any answers...

I'd just like to re-encourage you to ask your users to send a frown when this happens. (I know, I know, it seems lame. But hey, my contact was asking for confirmation if you'd sent a frown, so at least they're looking for it!)

Do you have offline files or sync enabled or something along those lines?

Niiiice. Thank you for following up. I'm sure this will help someone in future.
