If I need to remove the license file - how do I do that? and then how do I reinstall?

Office is updated, I get messages that I ned to upgrade which I do not want to do at this time as the version of office is only a few years old.

In Word, click Word on the main menu bar and then click About Microsoft Word. Which version is listed there? Do you still see 16.78.3 after having tried to update?

Did you try to explicitly install 16.83 via https://learn.microsoft.com/en-us/officeupdates/update-history-office-for-mac ?

I installed newer versions and now I can't even open excel or word. I'm getting the below with word and similar with excel.

Does anyone have a phone number where I can speak to a real person from Microsoft to help. I've called the 800 number and it tells you to got support online and then disconnects.

Getting desperate.

Mac is updated to Tahoe. I'm using office 2021 - word and excel versions are 16.78.3 and it does say the license is not active.

You have to install version 16.83 or later to run Office on your Mac. Go to the update history page at https://learn.microsoft.com/en-us/officeupdates/update-history-office-for-mac and find that version.

If both Save is greyed out and new documents cannot be created in both Word and Excel on Mac, the most likely causes in the provided guidance are Office reduced-functionality mode / activation issues or a broader Office installation problem.

Try these steps in order:

Check whether Office is activated

Open Word.

Select Word > About Microsoft Word.

Check whether it shows Activated.

If not, sign in with the Microsoft account that owns the Microsoft 365 subscription or Office license.

Refresh the license

Open any Microsoft 365 app such as Word.

Select Word in the menu bar.

Select About Word > More Info… > Refresh License.

Then fully close all Office apps and reopen them.

Sign out of Office, restart the Mac, then sign back in

This is recommended when Word and Excel are both affected, because the issue may be licensing-related rather than file-specific.

Reinstall Office from the Microsoft account installation source

Quit Word and Excel.

On the Mac, open a browser, go to office.com, sign in with the Microsoft account that owns the license, choose Install Office, and run the installer.

After installation, open Word or Excel and sign in when prompted.

Then test File > Save and File > Save As.

If saving still fails, remove Office license files and sign in again

This can help if the license state is corrupted.

After removing the license files, reopen Word or Excel and sign in again.

Make sure the correct account credentials are available before doing this.

Test in a different Mac user account

Go to Apple menu > System Settings > Users & Groups.

Create a temporary Mac user account.

Sign in to that account and test Word or Excel.

If saving works there, the problem is likely limited to the original macOS profile.

Install the latest Office updates

Open any Office app.

On the Help menu, select Check for Updates.

Enable automatic updates if desired, then select Check for Updates.

If the issue happens only with existing files and not with new ones after activation is fixed, also check these file-save conditions:

The destination folder must allow Read, Write, Modify, and Delete permissions.

Saving can fail if the disk is full.

Saving to an external or network drive can fail if the connection drops.

Antivirus software can interrupt the save process.

If another instance or user is saving the same workbook, the file may be locked.

A temporary workaround for an open file that will not save is to save it to an alternative drive or location.
