A long time ago, I answered a lot of questions in the so called Microsoft Forums assisting the community with VSTO issues. The forums still exist (https://social.msdn.microsoft.com/Forums/vstudio/en-US/home?forum=vsto), but are not the main access point anymore if you want to reach the Office Extensibility Platform team with your questions or issues.
These days https://www.stackoverflow.com is the center of the Universe (well… not really but if you have developer related questions it is … sort of …).
StackOverflow is a huge knowledge base of information formed out of an even bigger stack of questions from the community answered by not only the community but also from many of the ‘real’ product groups. If you are building your Add-ins using OfficeJS your can go to:
This “office-js” tagged group of questions is actively monitored by the Office Extensibility Platform team and you might recognize many of the team members as being the ones answering your questions (or apologizing if you reached an issue). By asking your questions in there the information around it is automatically functioning as future reference item.
You’ll notice, if you Google for a specific issue or question, that you’ll hit StackOverflow simply because you often won’t be the only one with that question. Big chance that the answer is already available and that will save you the time to submit the question.
Remember, that by submitting your question, you are not only helping yourself but you’ll help many others arriving at a later time with the same question.
And … while you are at it, try to answer some of the open questions if you know the answer. It will provide you ‘reputation’ points that may help you even more. The more reputation points you get the more you are ‘credited’ with features. If your reputation is high enough you’ll be able to moderate questions with a group of peer moderators, and if it is really high you can moderate without confirmation of other moderators. You basically build trust by doing good.
BTW, the office-js tag is not the only tag where the team lives, other examples and my favorite tags:
Note that VSTO is also in there:
so if you have questions on the good old VSTO tools this is your go to place
