Usually Inky adds Office 365 accounts without any problems.

If Inky fails to add your Office 365 account here are some things to check:

  1. Inky is not compatible with certain anti-virus software programs such as Avast, Fortinet, or Kaspersky.
  2. Some customers report they needed to have a web browser open and logged into Office 365 Mail the first time they add their account to Inky.
