Office 365 Support
As a user of various Microsoft Office products for decades, I know dealing with the the range of products is not always easy. If you have any problem with any of the Microsoft products, then you will need to use the list of support links i have compiled. Below are couple of different sources where you can get help for any of you problems around Office 365.
Office 365 Support Community
This is literally the first place, where I would start my search for an answer. No matter how strange your problem is, its most likely that someone has had it before and some of them went to the community where users post questions that get answered by experts ore even staff members.
This is the official support site for Office by Microsoft. So you can check out the numerous articles they have produced to help users that have problems with their product use.
Microsoft Support Line
Yes, Microsoft actually has a support line. Since this way of supporting customers is actually not very scalable, you might have some trouble getting through though. Microsoft has several different numbers for different problems, depending if you need support with word, excel, sharepoint or outloook. They also separate between technical and sales problems. Its best if you go and have a look. You find your way, since the site is well structured and will guide you to the correct contact.
Google Helpouts for Office
The Google Hangout could actually be a game changer for the whole thing but sadly, The platform have been shut down by Google since 20th April 2015. Usually, product experts are hard to come by in the internet simply because they have better things to do than showing us how to login to outlook.com and all that, right? With Google Helpouts, you can exclusively book one of those “Experts” for a session to bombard him with your questions. The database for experts is already quite packed and there are several of them offering their help specifically for Office 365 products, But they is no need checking it out since the Platform is down.
