RE: Word for mac crashes

Hi Jeremy,

According to my research, the issue you are experiencing is related to the office client. I found a similar thread which can be accessed by following the link below:
Track Changes and New Comment Crash

Our forum mainly focuses on the online related issues of Office 365 for Business. If the method mentioned in the thread doesn't solve the issue, to ensure that you receive the best support, it is recommended you post it in our dedicated Office client forum.

Thanks for your understanding.

Regards,
