Login Issues 


When attempting to log into your Office 365 account, you may encounter some sign-in issues. It usually happens when you type in the wrong login credentials. 

There’s a chance you used the incorrect username or password. First, check for caps lock and the spelling of the password that you’re trying to enter. As passwords are sensitive, a small change can still restrict you from logging in.  

Also, you should avoid copying them from anywhere (such as text files or Skype conversations). Instead, you can try to enter them manually.  

There is also a possibility that your administrator could have changed your password without informing you. You should get in touch with them to provide you with credentials that will allow you to log in.
