How do I use connect Office 365 via MS Exchange to a GNOME Online Account?

Question

I am trying to setup an online account that connects to my companies office365 but i'm getting the error: "Cannot fins WebDAV endpoint". I can normally connect and login to the account via browser. Do i need to install an additional connector to do this?

Solution 1

Am I right in assuming that you are using gnome online accounts? I had a similar problem in other distros, and I was able to replicate it on an Ubuntu 17.10 virtual machine.

After clicking the new exchange account button in gnome online accounts, I typed in my email and password and submitted. The following screen came up. (I switched out my normal email address.) See photo below.

^Before

After changing the custom username field to be my entire email address and the server field to be "outlook.office365.com" (this server name may not apply to you; to find yours, look in the settings of your webmail page), the configuration succeeded, and ubuntu asked for my password again to add it to a keychain. See photo below.

^After

Also, if you are using gnome evolution for your email, you may need to run the following command to install support for the exchange web server:

sudo apt install evolution-ews

I cannot comment so here's my answer!

Follow instructions of pcoppock1's answer, if it does not work:

• Try using outlook.com instead of outlook.office365.com.
• Use an app password instead of your main account password, expecially if you have 2fa activated.
  If you dont know how to create an app password, check this ms guide

Hope it helps!

This is what I've been doing, and this is what has not been working. Would love to see other answers!

This did the trick for my work account! Just had to make sure Custom > Username was an exact match of "Email" (including the org's domain) and that the server was set as described (it resets on each failure! IME).

This helped me get past the Code: 456 - Unexpected response from server error. Unfortunately, there's another error after that: Failed to find ASUrl and OABUrl in autodiscover response. This is on Ubuntu 20.10.

Ah, this is a known bug. See this answer, which links to this bug

Took me months of passive troubleshooting to do so until i stumbled upon this post, thanks!
