1831743 - TB not passing version number to MS Azure => not compliant (involves MS365; works for FF)

Status: RESOLVED DUPLICATE of bug 1697805

(Thunderbird :: General, enhancement)

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/112.0

Steps to reproduce:

IT services recently introduced some further security measures that require s/w to parse version numbers to Azure to ensure that 3rd party s/w is compliant. Apparently Firefox has this feature enabled but TB does not. Here is what IT services told me as to why TB is not compliant and does not work any more:

"The truthful answer to whether Thunderbird will ever be compliant is we just don't know. The issue lies with Mozilla not having yet implemented a feature now available in Firefox to enable the app to report back to Azure what version it is.

I suspect Thunderbird may have an inbuilt/embedded browser as this is something also observed in other apps."

Do you know if TB will be updated so that it will be compliant? I imagine this issue will become increasingly a problem. I have copied the error message I get when trying to access email.

Actual results:

Able to sign into the M365 but s/w is blocked due as unable to determine version number

Expected results:

successful login

A bug number or link to info about when this was fixed in Firefox would be helpful, every weird Microsoft condition takes forever to research.

@J.Bamber could you post the User agent string for Thunderbird as shown in the troubleshooting information on the help menu? It is the eighth item in the list.

Is the issue perhaps https://support.mozilla.org/en-US/kb/windows-sso as it is a relatively recent addition to Firefox.

I am actually thinking this is a duplicate of Bug 1697805 which was resolved in the 112 version. Or is it as I see no enable SSO in Thunderbird 115 as is a requirement for conditional access in Firefox. https://learn.microsoft.com/en-us/entra/identity/conditional-access/concept-conditional-access-conditions

But I am far from expert in anything related to Microsoft authentication.
