Why can´t I enter the License Agreement Number ?

After the first installation or an upgrade to a licensed version from an Evaluation installation Forefront Server products must be activated by entering the “License Agreement Number” (LAN), this code is provided along with the contract.



Recently we have got some calls from clients receiving errors while entering the LAN, where the LAN was 8 digits long and contained a letter before the 7 digits number, (e.g. V1234567, with a “V” in front). Antigen and Forefront Server products require only the numerical part of the LAN. To correctly activate the product we dropped the “V” and introduced the LAN as a 7-digit number (e.g. “1234567” without the initial letter).

  • How do I get the Licence agreement number as a technet subscriber ??


  • Hi,

    I have downloaded "mu_forefront_protection_2010_for_exchange_server_x64_cd_x16-11061.iso" from msdn and instructions says:

    "When customers install the product, they will be asked for an Agreement Number and an end-date. The Agreement Number can be the first seven digits of their TechNet or MSDN Agreement number. The end date is when they plan on ending their use of the product. "

    But when I enter the subscription number (first seven digits) and expiration date to activation window and click ok, I get alert box "The Expiration date is not valid"

    I have used first seven digits from my msdn "Subscription Number" as Agreement Number are those two numbers same thing? (Subscription number is 10 digits long, without 'V' in front)


  • We recently renewed our EA and this time we have been given an 8 digit License Agreement Number  (all numeric) and even the Microsoft licensing site list the number as 8 digit without alphabets. The Forefront products including TMG only accepts 7 digit. In order to accommodate the changes in licensing department will there be any updates to Forefront Products to support the new 8 Digit License Number?

    With Regards,

    M S Ali
