Hi Everyone,

I have been happily using thunderbird for the past 9 years at my institution (University of Utah), but this past Friday they migrated my account over to MS Office 365 ("O365"), and our IT group is not sure why thunderbird stopped working. They say that they don't provide support for thunderbird, but I did manage to stay on the phone with a guy for 45 mins or so to troubleshoot (with no luck).

I also have the "Owl for Exchange" plug-in installed, in case that has relevance here.

I specifically get this message: <<

-(

Something went wrong We couldn't find a mailbox for this recipient. Either they don't have a mailbox or don't have a license assigned. 

 >>

I tried removing, re-adding my account a few times, I also tried uninstalling/reinstalling thunderbird. Also played around with different protocol options.

Found this thread "https://support.mozilla.org/en-US/questions/1294759#answer-1332868" but I believe the chosen answer of changing security settings on "azure admin" is not an option for me, as I don't have access to O365 interface (as far as I know anyway).

I also tried other suggestions in that thread like changing the domains to outlook.office365.com and using a fake @outlook365.com email address, but that didn't seem to work. Any other ideas?

Thank you! Angela
