Office 365 Install Issues

I coordinate the IT for teachers and students at a small private elementary/middle school.  We use office 365 and some use PCs while others use Macs.  We keep getting sporadic notices that "We've run into a problem with your office 365 subscription and we need your help to fix it. We have the option of doing it now or later.  Any ideas?  I just got the message three times this morning and each time I have re-installed my office suite, which is basically what it looks like it wants me to do.

I would love any insight into the problem.
