Hi, 

Our users keep experiencing an issue where the Office apps stop working and require activation.  So far the only resolution we have found is to reinstall from image downloaded from VLSC.  Is there a better fix for this?

Thanks in advance,

Brad

Hi,

Regarding of the issue, please provide us more information to assist you better.

• Which version Of Office do you use? Office 2013 or Office 2016 for mac.
• How did you activate the Office via Volume License? KMS or MAK?
• Was there any error message?

As far as I know, the Volume Licensing customers will be able to download Office 2016 for Mac from their Volume Licensing Service Center in early August. If you use Office 2016 for Mac, I recommend you give a call to Volume Licensing Service Center and they'll help you re-activate Office 2016 for Mac

If you use Office 2013, please try to use the following methods:

Use the Office Software Protection Platform script (ospp.vbs) to check the states of Volume License first.

You can then run ospp.vbs /ddescr together with the error code to see the text of the error message. The text will help you better understand the issue and what to do to fix it.

Another way to obtain an error code is to run ospp.vbs /act on the client computer to manually activate Office. If activation fails, an error code will be shown.
