Hello Pleskians
We are already into this AutoDiscover topic for a long time. Two years ago we created our own AutoDiscover config for our customers because they were in need of it and Plesk did not have this feature back then.
Then we have worked with the Plesk developers side a side when the feature was developed and I'm really happy to see that the feature is now stable and working, since it was not properly working in the first version of Plesk AutoDiscover.
We have set up 3 different VMs to test the behavior:
Unfortunately there is still not everything working, but I personally think that the problem is on Microsoft's side. I'm posting this that we can start a discussion about the AutoDiscover behavior with IMAP servers in Outlook hosted with Plesk.
How I've already written above, our customers are using a unified domain for the mailserver. That means when customer XYZ with domain
On Outlook 2016 and newer (with the new account setup prompt - this one: Screenshot), Outlook does not even try to retrieve the settings. So no request is made to
This behavior is not really cool for our customers, since they then need to type all server settings in manually.
When checking the AutoDiscover settings for this domain, it does work perfectly. We have checked it with a POST request here and also with the Outlook AutoDiscover testing tool.

Does anyone know more about this? I hope I can start a good discussion here about AutoDiscover.

Now it is possible to change these settings via Panel.ini (explained here) and that's pretty cool.Unfortunately there is still not everything working, but I personally think that the problem is on Microsoft's side.

How I've already written above, our customers are using a unified domain for the mailserver. That means when customer XYZ with domain
customer.xyz has the email [email protected] the correct mail settings for him would be the following in our case:- Incoming mailserver: mail.ourdomain.tld
- Incoming port: 993
- Incoming protocol: SSL/TLS
- Outgoing mailserver: mail.ourdomain.tld
- Outgoing port: 465
- Outgoing protocol: SSL/TLS
- Username: [email protected]
On Outlook 2016 and newer (with the new account setup prompt - this one: Screenshot), Outlook does not even try to retrieve the settings. So no request is made to
https://customer.xyz/autodiscover/autodiscover.xml and Outlook directly asks what type of mailbox it is. After selecting "IMAP" it asks for the mailserver, port and protocol.This behavior is not really cool for our customers, since they then need to type all server settings in manually.
