mailbox | repo shows the steps

We have an Outlook add-in with a task pane that can be opened for messages in Read mode to perform an action on the message. This works fine for messages in the user's normal mailbox, but the button to open the task pane doesn't appear for messages stored in a separate PST file.

Is it possible for add-ins to activate for messages stored in PST files? I suspect the answer may be "no", since all add-in buttons (including the "Get Add-ins" button) disappear as soon as I navigate into a folder from the PST file.

I've tried adding true to the manifest just in case that setting also applied to PST files, but it didn't help.

This scenario doesn't seem to be explicitly mentioned in the list of items not available to add-ins.

I'm developing an AWS Lambda function which will need to access an Outlook 365 inbox at a regular interval. I'm using Graph API for accessing the inbox.

I created a new Azure AD web application registration using the Azure Active Directory admin center.(https://aad.portal.azure.com/) When assigning API Permissions to my app, I have an option to choose between Delegated permissions and Application permissions. I can't use delegated permissions since my code will run without any user interaction.

When choosing application permissions, I can't find a way to restrict the permission to one user account. For example, if I try to give the app Mail.Read application permission, it'll get access to all mailboxes in the enterprise. Or maybe I'm interpreting the permission description incorrectly.

How do I give my app API permissions to one user's mailbox?

I use EWS to get data about user calendar events. I connect to MS Exchange on behalf of the user. If I connect as user B, how can I tell if I found the same calendar event which I found before in mailbox of user A? Maybe something like the same message identifier or something like that?

My company is using Microsoft Exchange server 2016. Each mailbox only has 1G space allocated. How can I get the mailbox usage information using python exchangelib?

I am using Python 3.9.5 with exchangelib 4.4. I can use exchangelib to send and receive email however, cannot find the right way to get the mailbox space.

I have the following code moving all emails in a folder to the "Old" folder using Mailbox package:

How can I find which Outlook build numbers/versions correspond/support the different Mailbox API requirement sets? I have an add-in that requires the API requirement set 1.8 or higher, but I do not know which Outlook versions/build numbers correspond to this API requirement set.

I am trying to create a outlook plugin in React JS to detect mail selected or mail selection change.

Tried Mailbox EvenetType ItemChanged, add handler for event is return success but handler not called when user select or change selected mail from list.

The code I used is as below

I am having an issue with SmtpClient in an ASP.NET web application.

I have a generic function that builds an email message and then sends it. The code is as follows:

Scenario I work for a company that uses ServiceNow and integrates with Outlook calendars for various employees/job bookings etc.

When we take on a new employee which happens very often at the moment, I have to create them in Office 365 as you would expect, I then have to add them to various groups and then create a new calendar with that users name inside a shared mailbox.

For example > Access shared mailbox abc@example.com > Calendars > New Calendar > John Smith Appointments

I then need to give (in this example) John Smith Edit rights and another few management edit rights to that calendar so they are able to schedule appointments for John Smith.

It's a faf to do so I thought lets write a script.

What I have so far is I have a powershell script that asks for the first and last name, then it goes off and generates a user, adds them to the correct groups.

What I am struggling with is how do I create a calendar in the shared mailbox using Powershell.

I'm competent adding the permissions etc that's not the issue, but I can't seem to find out to create the calendar in the first place!

Any help would be greatly appreciated.
