Terms & conditions

3 month's free Microsoft Office 365 subscription to O2 SME and LME business customers terms and conditions

This offer is available to O2 Business Customers who are classed as SME customers (i.e. businesses ranging from 1 - 200 employees) or LME customers (i.e. businesses ranging from 201 - 2000 employees) who are signing up for a new Office 365 subscription upon the acceptance of the specific terms and conditions set out here. Customers must take out a business mobile, tablet package, or broadband package to qualify for this offer. This offer excludes the Small Business plan for Microsoft Office 365 at £3.90 per month per user.

This offer is only available when offered by an O2 account manager. If the customer terminates their business mobile, tablet package, or broadband package or their business mobile, tablet package, or broadband package is terminated for any reason before the end of the free trial, the free trial will immediately come to an end.

O2 reserves the right to change or withdraw this offer at any time. Contracts must be entered into before the offer is withdrawn. If we withdraw this offer we will include an update confirming this at the top of these terms and conditions. The offer is only available via our SME and LME account managers.

Eligible O2 Business Customers who sign up for an Office 365 package will receive their first three month's subscription for Office 365 free of charge.

The free of charge element will appear as a credit on the customer's invoice for the same amount as the monthly charge for the relevant Office 365 subscription cost in the first three months. Usual line rental, call and other mobile charges continue to apply. Standard charges will apply automatically after this initial promotional period.

No cash alternatives are available. The offer is only available for new subscriptions. Depending on the different subscriptions, the number of separate Microsoft Office 365 licences available to each customer will vary. For the avoidance of doubt, any additional licences added after the first licence within the first three month's will only benefit from the free access to end of the initial free period.

O2's Standard Business Tariffs and Terms for Microsoft Office 365 will also apply and are available at
