I need to create an outlook addin that will do the things I listed below before sending a meeting request:
Check how many users are in the To list, warn if there are more than predefined number of users
Warn if subject line is empty
Warn if word "attachment" is used in mail body but no attachments can be found in the mail
Is it possible to do this with Office Interop or with a VSTO addin? I need to intercept and cancel the sending of meeting request if one of the rules above doesn't meet.
Thanks.
You can do it with VSTO. I did use it in the past to make an outlook addin to add a dynamic signature to a message before send it. You can subscribe to events to check your rules, and allow or cancel your meeting request.

I am working on an Outlook addin to make sure confidential information is not leaked using mail.
Using the on-send feature using ItemSend, we were able to get the email fields and block the sendmail, if required

But there is an use case
User composes the mail and saves it to draft (without clicking on Send)
In outlook on web, composing a mail saves to draft automatically.
How can the add-in get a callback when draft is synced to Outlook server ?

There is no such callback available for web add-ins. You may post a feature request or suggest a feature on the Tech Community site where community members get to share ideas on ways MS can make Microsoft Graph and Office Platform better by sharing feature requests and ideas.
Nothing like that for the JS-based addins.
For the COM addins, OOM exposes MailItem.Write event - your event handler can cancel the operation.
I am writing a script to reply to AppointmentItem in outlook. The AppointmentItem does not expose ReplyAll (or Reply) method, and that is only available for MeetingItems. However, all the events on a user's calendar are stored as AppointmentItem class, even if there are multiple attendees. I am wondering how I can ReplyAll to an AppointmentItem? Is there any way to get the associated MeetingItem?
PS: When I right click on an AppointmentItem in Calendar it does enable ReplyAll, so there should be a way to do this.

Currently I am developing an Add in for Outlook and I have implemented onSend event. Since it is UI-less and it is always triggered, I was wondering is there a way to only trigger it for Appointments not emails? This is because user experience, for them not to have "Add in" triggered when messages are created and sent out.
There isn't a way to restrict On-send to just appointments. One workaround, which I'm sure you are aware of, is to no-op the event handler if the item is a message. This doesn't solve the problem of the add-in running on messages.

I have a business requirement where there is a need to extend the functionality of outlook.
I am exploring Office Web Addins for this requirement.I have following queries.
I need to automatically move all incoming email to an external location.Does Office JS API provide handlers to incoming email event?
If it possible to define an action with Office JS API , which when triggered can loop through all the current unread emails and perform some action on each email (like move certain emails to a certain external location )
Is it possible to append custom headers to a email being composed using Outlook web add-in?
No
You can use EWS for that
No.
If your code only needs to run under the Windows version of Outlook, a COM addin might be a better option.
Unfortunately, it seems not possible to meet your requirements using Outlook Web Addin.

I want to put emails the user receives in a sort of "review status" in my app and let users choose manually if they want them to be let through.
For this I need to filter network traffic to withhold emails receivef with the IMAP protocol from Outlook and send them some time afterward. And to the same for emails being sent.
Would this be possible to do on Outlook on Windows 7/8? Or would I be unable to make Outlook receive the mailing after I filter it out?
The Outlook object model doesn't provide anything for foltering emails.
Instead, you may consider handling the new email programmatically in the code handling the NewMailEx event which is fired when a new item is received in the Inbox. For example, you may develop a VBA macro for doing any customizations in Outlook programmatically. See Getting Started with VBA in Outlook 2010 for more information.
