We could not copy the content to the Clipboard, it is in use by another application. You can still paste your content within this workbook but it will not be available in other applications.

Control Panel> Mail

changed/remade contents of all 3 buttons.

I found success with

Task Manager

select Task Manager

Delete Task Manager

Select Reboot

Turn off Fast Boot

Accounts

turn off copy previous settings on restart

Restart

Success

Used suggestion on turning off Fast Boot

along with turning off copy of previous settings on restart.

(In prior aid from others, a Process gets started under Task Master

gets interrupted and leaves process hanging)

Good Luck

My thought exactly... work-arounds only indicates a problem or a flaw in a process, or in this case, the applications. The fact that many of us are experiencing this should motivate Microsoft coders to fix the problem before it all goes haywire.

@Vimzie ~ sure it could be a Clipboard problem, which would make it a system problem, but I am only experiencing this with Excel which leans toward a higher probability its Excel.

I have renounced to buying the desktop version, since my experience with Microsoft 365 is not what I was led to believe... the integration of OneDrive with backups and autobackups connectivity slows down my sessions or causes hiccups at time, its like solely an online working experience. Sometimes, Excel just crashes in the middle of my work . . . this is unlike the desktop Excel versions I have ever experienced. I used the 2010 version for a long time and it never faltered. I only switch because of Excel newer features and also thought the subscription to be a better bargain.

The minute I get the cash to buy the desktop version, I am switching. As far as I am concern, Microsoft Office 365 is still not ready for prime time.

No solution here. I re- did the the mail contacts. looking into reg. for protocol TS 2.0 checked.

Reloaded MSA 365 Outlook.

Clean new sandbox with different behavior.

Starting on path from close to the beginning.

Not a proud moment for me.

This now closed.

@Advance1sh - Me either.. never had this happen before.. but that troubleshooting for another day. But yes, I have Admin rights and I did go into Properties as a workaround, to no avail. i return back and he Read Only box I unchecked is still checked... so I need to figure out what's going on with that first before I can proceed. If it is not one thing is another....

Omar - not sure I understand why you can't proceed. Are you the admin for the PC? On mine, another way to proceed would be to go in via the security tab on Properties and selvct the appropriat eoptions there.
