Question

Cannot login to Teams via my Business Account

Channon Coaching 0

Hi there I have 2 accounts a personal and a business both have the emails

When I try to add my business login to teams I can't it keeps throwing this error and I'm stuck going around in circles (see below). I've tried deleting, clearing cache, removing my personal account but everytime it just reloads my personal account and when I try to get into my business account it gives me this - super frustrating.

Can you help?

Hi @Channon Coaching,

Thank you for posting your question in the Microsoft Q&A forum.

Based on your description, it sounds like you have both a personal Microsoft account and a work/business account using the same email address. This can sometimes cause sign-in conflicts in Microsoft Teams, where Teams repeatedly picks up the personal account instead of allowing you to sign in with the business account.

As a first step, I recommend changing the email alias of your personal Microsoft account to avoid the conflict:

Go to the Microsoft account aliases page: Manage account aliases
Sign in with your personal Microsoft account (not your work account).
Select Add email.
Create a new email alias.
Set the new alias as your Primary Alias.
After the change is completed, use the new email address when signing in to your personal Microsoft account.

You can also refer to this Microsoft article for additional guidance: Add or remove an email alias in Outlook.com

After changing the personal account alias, please clear the Microsoft Teams credentials, then try signing in again with your business account:

Remove cached Teams credentials

Close Teams.
Open Control Panel > Credential Manager.
Select Windows Credentials.
Remove any entries related to:
- Microsoft Teams
- Microsoft Office
- Microsoft 365
Restart the computer.
Launch Teams and sign in with your business account.

Thank you again for your time and understanding. I really appreciate your patience, and I'm here to help. Looking forward to your response!

Hi @Channon Coaching,

Thank you for the update.

Since you have already changed the personal Microsoft account alias and cleared the Keychain on your Mac, but are now receiving the message:

"You don't have the required permissions to access this org. Talk to your IT admin for more info or switch to another account."

this may indicate that the issue is related to the Microsoft 365 license or access permissions assigned to your work account rather than a cached sign-in conflict.

Could you please confirm which license has been assigned to your account? You can check this by signing in to My Account:

My Account

After signing in, go to Subscriptions and review the licenses assigned to your account.

If you do not see a Microsoft Teams-compatible license assigned (for example, a Microsoft 365 Business, Enterprise, or Teams license), please contact your organization's IT administrator and ask them to verify that the appropriate license has been assigned and that your account has permission to access the organization's Teams environment.

Thank you again for your time and understanding.
