New Outlook can't find Microsoft 365 mail server on a new PC
Dear community,
first of all: I like the New Outlook very much. It worked fine for several months on my old laptop but now I have a new one and have to install it.
My company is using Microsoft 365 and our mails are handled by Exchange 365. Our mail adresses are like email address removed for privacy reasons where "our-company.com" is our domain name.
Now I installed Office on my new laptop from the website of 365. I wanted to configure "New Outlook", but I got an error message saying, that the mail server can't be found and should try it again. I tried to select the account type manually. Same behaviour. The "Troubleshooting" button also doesn't help.
Then I configured Outlook Classic as a next step and that works fine! Then I tried the switch "Change to new Outlook" (my original text is German) thinking that this will transfer the working configuration. Same problem: "mail server not found".
I ended up in the situation, where nothing works. "Outlook Classic" wants to start "New Outlook" and "New Outlook" can't find the mail server without giving me more options to change the configuration manually.
Why can't "New Outlook" find our MS 365 hosted Exchange??? Outlook Classic and the rest of the Office apps including teams work fine with my account.
Other networks (home, hotspot) didn't help. So it is no problem of our company network.
I have to uninstall "New Outlook" to escape from this infinite loop.
Any help is appreciated!
Thank you,
Stefan
