BING ADS POLICIES IN DETAIL TO RUN TECHNICAL SUPPORT PAID CAMPAIGNS

After multiple complaints from customers about companies which have been Microsoft partners, and using the Microsoft trademarked terms and images Bing Ads editorial team has chosen to disallow all advertisers, partners or not, from using any Microsoft intellectual property. This includes any and all trademarked and copyrighted terms, logos, and images for any and all Microsoft products.
As for the misleading material, this typically relates to how things are worded on the websites.
This also includes a disclaimer which Bing Ads require  on each landing page.
The disclaimer must be clear, prominent and within close proximity to the first call to action, and above the fold so no scrolling is required to view it. This must also include the following criteria:

•       Call out that the company is a 3^rd party support provider.
•        Call out that the company does not own any of the brands supported.
•        Call out that the service may be offered through the brand owners.

Below is an example of a complete disclaimer which meets Bing Ads editorial guidelines.

Disclaimer: Company name is an independent service provider of technical support for software and hardware. We have no association or affiliation with any of these companies and brands for which we are offering support on Company name. Usage of logos and brand names are just for information purposes. All other trademarks, registers trademarks, company names, product names, and brand names, are the property of their respective owners. The services we offer may also be available through the brand owners, on their sites.
There are some services that cannot be offered or supported. These include support for any email services. This includes, Hotmail, Gmail, Outlook, Yahoomail, and many more.
Another service which cannot be offered is for resetting passwords, or helping recover forgotten passwords as this is a service which can only be offered by the brand owners.
Any time a brand name is used it must say "Support for Brand Name." This is because when an ad or site says "Brand name support" it can mislead a customer into believing they are contacting the brand themselves.

In addition to the disclaimer Bing Ads also require a privacy policy if collecting a customer's personally identifiable information (PII). Personally identifiable information (PII) is any information which can be used to identify an individual person.
Examples of PII are:

•          First and last name
•          Cell Phone number
•          Email address
•          Mailing address
•          Credit card number
•          Social security number
•          Driver's license number

A privacy policy or a clearly labeled link to a page containing the policy must be placed on the landing page, and on any page which is collecting PII.
Bing Ads  require a few components to be in the privacy policy. These include:

•          Clearly state the name of the company collecting the information.
•          Clearly state the reason why the information is being collected.
•          Provide opt-out or unsubscribe instructions specifying who and how to contact them to remove them from receiving any communications from supplying their information.

As of February 2015 phone numbers can no longer be used in the ad copy. If you wish to have a phone number display with your ad it must be added using either a call extension or location extension. Phone numbers will no longer be able to be used within the ad title, ad text, display URL, or destination URL.
Once the ads and website have the necessary changes made to fall within Bing editorial guidelines Bing Ads team will reviewed once again by to get the ads approved.
