New Outlook won't let me add my outlook email account.

I'm having this same issue and have tried everything I can think of. My account that I'm trying to log into the new outlook is an outlook account. When I try to sign into it on the app it loads for a long time and then states "Outlook does not yet support adding Shared Mailboxes this way. Try adding another account." I'm not able at all to figure out what this means or how to fix it.

Hi,

I found a different solution that worked for me. First I went to "Credential Manager" in the control panel and removed all the references to the email accounts in question (had two emails that reused to add to the new Outlook), after I went to my microsoft online settings for each account, in "Your Info" > "Sign-In Preferences", to have a look at what alias I had in there, but I didn't have any, was just using my regular email address and set as primary, so I decided to create a new temporary alias and login with that in the new Outlook app.

This failed on the first account but when I loged in again (on that account) but using the previous alias it worked!

I then tried doing the same process with the second account, and logged in with the alias which is this case worked straight away,

I guess adding that alias forced some refresh on the account sign-in preferences that allowed it to work after.

Since using this app as a beta it had never worked! I now have both accounts added and they show the old primary alias that I always had.

I truly consider this new system an intrusion and an abuse of rights to use when I paid for this. New outlook email has taken over and managed to load an absurd amount of emails into an account I've had for over 18 yrs. and now does not allow me access to that account where I receive my most important mail. It is MS programmer's pipe dream to keep drawing high salaries for this lncredible **** of computer science. This new outlook does not work for me or any other user. Please fix it or throw it in the garbage where it truthfully belongs.

Hi Segunfunmi,

I am unable to add an outlook.com account in MSoutlook on Mac. It was working fine till yesterday. Suddenly started asking for password. I entered the password, but it kept on saying invalid credentials. So I went to outlook.com and reset my password. I can login from the web, my phones etc., but MS Outlook keeps on giving invalid credentials error. I deleted the account, now I am trying to add it back, but it won't let me.

I have logged in using the credentials to leave this comment, but MS Outlook won't allow!

Frigging Microsoft and its crappy applications.

Thank you for your help

Best Regard,

Karan
