I'm trying to develop an outlook Add-in, when the addin button clicks it open a windos form. The windows form has a text field, In the text field when a name is typed it should show suggestion list as in outlook email "send to" field. I'm struggled with finding any source to read. Can anyone help :) ?
The SendTo list is pulled from the autocompletion list cache and is handled differently based upon Outlook versions. In Outlook 2010, you can use the Suggested Contacts folder, whereas in Outlook 2007 and below it is contained in a hidden NK2 file.
See related link on how to manage the autocompletion cache.

It's my first time developing add in for outlook, i'm tryng to do an add-in that interact with outlook calendar to find an appointment, but i can only show up the add-in when i create new appointment, is there any way to show it outside compose and read context? like viva insights do?
i found that this can be done with VSTO, but i need it to work also with web outlook and other os, if someone can help me to figure it out i will apreciate.
i tried to do it following the add-in doc
https://learn.microsoft.com/en-us/office/dev/add-ins/outlook/outlook-add-ins-overview#extension-points
i can't find an extension point that fits my purpose.
Thank you
Add-ins are only valid in Mail/Calendar individual item context currently. Hence, if no item (email / event) is selected, addins do not show-up or work - it does not know in which context it is suppose to run.
If your scenario requires it to run without email/event context, we suggest you to file a feature request here: https://aka.ms/M365dev-suggestions
I've been trying to activate my add-in when the user open his email so I can analyze it. I found one example in on add-in from another company (Retruster). The issue I didn't found way to reproduce the action. Someone knows how to reproduce this event? Because I just found when sending a message.
The labels shown on the YouTube video are categories set on emails. They can be set on the Exchange server side when your message arrives without any add-in involved. Remember, add-in activation rules are described in the manifest file - it can be regex filters, known entities etc. Read more about them in the Activation rules for contextual Outlook add-ins article.
The add-in starts working when the user clicks on the ribbon button.
Is it still possible to use Outlook URLs to open Open Outlook items such as Calendars or Contacts as per the below article...
How to open Outlook Calendar from an email link or webpage?
If you register the Outlook protocol like described in the Shortcuts and the Missing Outlook:// Protocol article you can open items.
You can link to a globally unique identifier (EntryID) that is created for an item and doesn’t change when you rename or move it:
Outlook:000000000EAE44133243899468AC478B31C0BANDHEWR324
It is best to use the GUID URL since you don’t have to worry about changes breaking the link. If you are after a outlook message, all you have to do is select that message in outlook, and then left-click on the linker icon on the lower right of the taskbar so that the link will get copied. Next, you will just have to paste it somewhere. It works the same way for contacts and even calendar events.
Hello Outlook/Microsoft Team,
I would like to ask if there is a way to add our add-in icon to the "easy-access-toolbar" as shown in the image below. This toolbar (of outlook add-ins) is shown whenever you are reading email via the browser. Unfortunately, I could not find any guide or documentation on how to add a custom icon in this list.
After some investigations, I found that only add-ins from the market are added to this. Is my understanding correct? Or can a domain admin set this up? Or does this require a manifest entry?
Our outlook add-in is used exclusively by "enterprise" accounts. Thus, we did not deem it necessary to publish with the add-in store.
Thank you for your support and understanding.
I'm trying to create an Outlook Add-In that will forward the selected mail message as an attachment when the button is pressed. Preferably this will work both for the Outlook Client, and Outlook Web Access. To do this, I need to add a button to the main UI in Outlook which shows the list of messages.
However, within the new Add-In format, I don't see an ExtensionPoint for Outlook that allows adding a button to the main mail UI.
https://learn.microsoft.com/en-us/office/dev/add-ins/reference/manifest/extensionpoint#extension-points-for-word-excel-powerpoint-and-onenote-add-in-commands
There are options for the MessageRead pane or the MessageCompose pane, but I don't see anything for the general overview.
However, the following New Feature complains that multiple mail items can't be selected with the add-in syntax, which seems to imply that a single mail item can be selected. If a single mail item can be selected, then that implies that there is a way to add a button to the overview mail page since that's the only place mail can be selected.
This makes me think it is possible to do this, but I'm not sure how.
Can someone please point me to how this might be done?
NOTE: I am NOT trying to create a COM plugin. That is the old format and I've noticed they're increasingly less reliable in Outlook 2016. I am trying to use the new format.
The MessageReadCommandSurface and MessageComposeCommandSurface extension points for Outlook applies to both the main Outlook window (the Explorer) and the item (Inspector) windows. The Explorer Ribbon buttons activate when an email is selected, so the buttons interact on the selected email. So you don't have to do anything if you've already defined those extension points.
