Had an Office 365 Home Trial used with my home and yard-mail address and wanted to switch to Office 365 University. No sooner said than done: The server seemed to know the whole procedure and pointed out to me what I lose in comfort, if I really do like this: Say to reduce by 5 PCs on only 2 PCs. It confirmed to me also that the product has a University License 4-year term. A verification of the university ran perfectly and my email address was for University unlocked - and then began the disaster. The final step is simply came just a nothing-meaningless error message and I should like to address the support via a link. The online help did not include my problem and for "other issues" we came to two other questions back to the beginning. Neither on the imprint nor via "contact", or anywhere else on this side or on Microsoft.de - even after the benefit of search I had no contact possibility to found Microsoft. No phone number, no e-mail address. Googling revealed "unofficial" numbers that were sometimes unavailable, led me to the United States or otherwise. Eventually, I cried at night time shift in the United States, to be told that they could not help me. At some point I had - after the fifth number - the activation hotline from Microsoft on the phone. Google said I should behaarlich try to get someone to answer the phone. After about 10 minutes speech and "press" had I times a queue that only brought the announcement to me after 30 minutes on hold: "Unfortunately, all employees are talking order you not to take more to complete, call your time. but tomorrow or at a later time once again to ". After that was launched. I had bitten almost to the phone. After another attempt only came out a manned. I spite of many call attempts in succession, displaced hourly, over a number of times (morning / noon / afternoon) distributed a total of three days and loosely 100 attempts needed to get employees to answer the phone. The problem was that the server had an error and an email address at which a 365 Home SUBSCRIPTION had been used previously, is to use no 365 University SUBSCRIPTION. I should use the Key to a new email address and then functioned well. When asked why that was to be found neither on the website, nor anywhere else, it was quite matter. "I do not know, I can only tell you how it is." The remark that I use my email address for years and the entire SkyDrive cloud would move with it, and that would mean even more time and effort, was also dealt with quickly: "Unfortunately, there is no other way They either use a new email. address or you do not use the software. " If software would not be ruled out in front of Exchange - I would have given it back. But it got even better: barely hung up, I could not verify the new product on the new E-mail address: "Your product has been verified with a university" - and when you enter the Keys for a new E-mail address: "Please verify your product ". Of course, for the day was no more to be reached by telephone. This time, however, I was luckier: the next morning I had someone on the phone, which an email with the instructions for a "alternative verification possibility" contained me. The verification was already made at the server not be put back "that would basically not provided by the system - we must work with the workaround". After just under one week, one hour long SkyDrive relocation, new e-mail address and two new gray hair, and a Riesenwut on Microsoft, I now get activated the product. Microsoft: Who programmed with you, should be dismissed: stupider It really can not now !!!! :-( --- The software itself, you get it for times to run, is just Office. I think about it I do not need to tell ...
