What our users said about Owl

“My company moved last week to a multi-factor authentication (MFA), without any possibility to use “app-passwords”. So we were stuck…

Your solution with Owl is easy to configure.”

Alban

Alban France

“I just wanted to send you a “big thanks” for “Owl for Exchange”. It is finally solving a big problem with an Exchange server.

Finally, this add-on cures a big pain point I had for over a year now!”
