How do I fix my Office 365 subscription?

Alright for you to fix your subscription on your Office 365, you have to consider few things. Some of these are the following:

1. Is your subscription still active?
2 Where did you purchased it - online or using a disk to install it?
3. What are the things you are doing before it happened?
4. Did you install third party software?
5. Is there a windows update happened?

So for us to narrow down, you have to think of those questions. First, make sure the subscription is still active. Second, if it's online you can uninstall and re-install it again. Third, did you change some setting on your computer, you can do a system restore or reset. Fourth, if you installed something on your computer it might cause glitches so you can try to remove it and see if it fix the issue. Fifth, there are instances that windows update messes everything on your computer. You can check if there is a windows update on-going. Or you can also update it.
