Office 365 Outlook connector no longer working

This connector has worked fine for probably a year but has recently started failing and I can't get it to reconnect.  Errors are "Some of the connections are not authorized yet." and "Test connection failed."  I can't find any further details.

 

More info and troubleshooting steps I've taken:

  • Our company uses Exchange Online (E5 license).
  • I am able to long in and use Outlook (web) successfully with the account.
  • The account's password never expires.
  • There are no DLP policies applied to the environment, so no connectors are blocked.
  • Choosing to use another account but then entering in the same account's info (to reauthenticate) doesn't help.
  • Choosing another account works fine, though I need to get email from this account.

    Re: Office 365 Outlook connector no longer working

    The cause of the issue was an OWA policy blocking connections to Outlook from non-approved IP addresses.  When I am working from home, I am unable to edit and save the flow because it makes a test connection to Outlook at that point, which fails because I am not coming from an allowed IP.  The solution is for me to hop on VPN or be working from an office location.  The Outlook connection test will then succeed and I can save the flow.  Once the flow is saved, it runs fine on its own.

     

    So again, the error was only occurring when I was editing the flow while working from home. I haven't done enough testing to see exactly what changes I can make from home without breaking the connection but OWA policy was the culprit.

    I believe I fixed the problem by applying a data policy to the environment, allowing the Office 365 Outlook connector.  As mentioned above, previously there was no policy applied to that environment.  I thought that would have allowed all connectors but 🤷🏻‍♂️.
