Problem with HotMailbox setup

Mateusz, what version of WEBCON BPS do you use? It can be a supported TLS version problem.

Other question about your network environment:

Has your server direct access to the public internet? If you have a proxy in your environment, you have to configure it (proxy) in WEBCON BPS Designer Studio or configure direct access to Exchange online servers.

Server has direct access to the internet. There is no proxy. It has to be related with tenant, because when I used my own account (from my development tenant) there was no problem with coonection.
Current version: 2020.1.3.371

Hello Mateusz,

I am facing a similar error. Was there a solution on this one for you?
License of the user was upgraded from Exchange Plan1 to Business Standard, but no luck.

I did also a test on testconnectivity.microsoft.com and saw that there was a MAPI Error when looking up the Accounts Name in the addressbook, which returns the 401 response. But I did not get any further than that...

Best regards,

Tim

Update on this:

With the last update, it is possible to select MS Graph as authentication method. I will continue with this approach, since Microsoft will discontinue Basic Authentication in October 2022
