Now to activate: For me no problem and done within 5 minutes. Windows ID already existed and the activation was carried out on the university e-mail. I must admit, however, that the list of higher education institutions is very confusing. So the University of Bonn is there out under "Rheinische Friedrich-Wilhelms-Universität". But should not be a problem.
Before buying I have also given me because of the negative comments on here worried about the "shelf life" of the license. Me has been confirmed by Microsoft, however, both on the phone and e-mail, that the proof of eligibility is done only once. Corresponding comments that say the opposite, I can not understand therefore. Especially since I have not heard of any case in which actually had to be reactivated.
That would make no sense. It is here alone to proof of eligibility at the time of initial recognition! Then you have the key and is left alone. Microsoft sells this product but not as low as it takes pity on poor students. Here graduates to be "hooked" with a cheap product to make favorable decisions later as "decision-makers" for MS. Who has spent years with Outlook, will be difficult to persuade to Thunderbird. With a pesky licensing model that an annual activation requires MS would still urge people to only open source or pirated.
Microsoft would be well advised to eliminate this ambiguity in terms of activation. I would be deterred by the negative comments here almost from the purchase.
