Hello from Austria!
I bought office 365 about one week ago. Till now i only installed it on iMac and everyday i have the problem that i can't start word/excel/powerpoint without the prompting for activation appears.
In my portal page I can see that office2011 for Mac is correctly installed and activated , also that i use 1 of my 5 licenses.
What i did:
I downloaded office2011 for mac from the portal page and installed it correctly on my 2013 imac. After the installation i entered my e-mail and password and everything worked. After the fifth restart i needed to activate my office again. This also happened the next day. After 2 days i had a look in my portal and saw that 3 activations for the same computer were active. So i deactivated every installation, completely removed office from my mac (like described in the kb article), downloaded office2011 again from the portal page, installed and acivated it again. I restarted my mac and everything worked.
After the 4-5th restart i have the same issue. Office needs to be activated again -.-
What can i do? It is very annoying to enter my credentials nearly everytime i start one of the office applications.
Thanks for your help.
Alex
