Does anyone know if there are any changes in the permissions or behavior between this version and previous ones that could be triggering the admin approval process?

Any insights would be appreciated, as this information is needed to move forward with our IT team's approval process.

I understand Thunderbird version 128 ('Nebula') introduced significant updates, including new MS Exchange integration features, but these updates require additional permissions. As a temporary workaround, I reinstalled version 115 and set up the profile, which continues to work even after auto-upgrading to 128+. However, I need to convince my IT team to approve the new permissions for Thunderbird 128. Could any experts provide more details about these permissions and why they are necessary?

@jenny, are you still stuck?

@Wayne, Yes, I still have the question. Could you please provide more details about these permissions and their importance? My IT team needs this information for the approval required. Thank you!

Does https://support.mozilla.org/en-US/questions/1451561#answer-1660521 help?

@Wayne, Thanks for the help. The answer provides useful guidance on setting up OAuth2 authentication in Thunderbird, which might assist with integrating Microsoft accounts. However, it doesn't specifically address the IT approval process required for the new MS Exchange integration in Thunderbird 128, which is my main concern.

I don't know how, but I missed that you are trying to do exchange. v128 does not yet have exchange support. See https://wiki.mozilla.org/Thunderbird:Exchange

Hi Wayne,

If I understand correctly, Thunderbird 128's new Exchange features introduce additional security and access requirements, prompting organizations to review and approve permissions to secure sensitive data. In contrast, Thunderbird 115 doesn’t need these extra permissions, as it lacks the advanced Exchange integration in version 128. Could you please confirm if this is accurate?

Thanks, Jenny

Hi Wayne, Could you please confirm this? Thanks a lot!

Hi Wayne, Could you please confirm this? Thanks a lot!

I have clarified in the document https://wiki.mozilla.org/Thunderbird:Exchange

Hi Wayne,

Thank you very much for your help.

I understand from the document that Exchange integration is limited to beta builds. I installed Beta version 133; however, I’m encountering admin approval prompts in both Beta version 133 and regular version 128, which weren’t required in version 115.

Could you please clarify what specific changes were introduced in version 133/128 that now require these additional permissions as shown in the screenshot? This information will help me address my IT team’s concerns.

Best regards, Jenny
