We encountered a random error when trying to schedule Teams meeting via Outlook add-in. When the user clicked the New Teams Meeting icon (on the ribbon) they received an error message:

 

"Sorry, you need to sign out of Teams and sign in again before you can schedule your meeting. If the problem persists, please contact your support team."

 

I'm wondering what was the cause of this error. User was able to signed in after pc restart.

Possible the add-in / Teams got an update if I had to guess.

I have the same error. where has the create Skype Meeting gone

anyone have a fix for this yet?  I'm getting the same thing.

 

Re-starting PC didn't help.  

Signing out of Teams didn't help.

Un-installing and re-installing Teams didn't help.

 

I can no longer create Teams meetings from within Outlook.

We've had one of our staff report this too.  It started occurring when I switched him to Teams Only mode, but now, despite turning him back to Organisation Settings (Islands) he's getting the same issue.

 

I know in the past the Outlook addin didn't like working through authenticated proxies, but if it worked in the past but stopped that sounds like something to raise with support. I would make sure that you are on a current version of Outlook (Semi-Annual or Monthly), and uninstall and reinstall Teams first.

@Steven Collier  Any Update on this ? is there a workaround or quick fix for this? 

Thanks

@May_Rivers Hi May- the only update I have seen on this issue is some documented known issues by Microsoft involving MFA and using the Teams add-in - "To use the Outlook add-in, you must sign in to Teams using multi-factor authentication (MFA). If MFA fails halfway through the sign-in process, you'll still be able to sign into Teams, but you'll get an error message when you try to use the add-in. "

 

Let me know if this helps!  Thank you.

@May_Rivers on what? AFAIK authenticated proxies are not supported for the add-in.

@ArnoldD 

 

I was able to resolve this issue in our work environment by clearing out the local Windows Credential Manager cached items. If you're behind any environment that uses MFA or SSO... the current credentials stored may be corrupt on that users local profile. I was able to confirm that the web version works so this made me check out the local credentials. Once I purged those, The addin worked successfully. 

I know this reply may be super late... but I figure I'd share. Thanks.
