Hi Rogelio,

When you create the appointment in Outlook calendar, do you create it in the calendar of every attendee (in your example, do you create three appointments with three web requests)?

You can create/update an appointment in some else's Outlook calendar if you use credentials of a user who has write permission on this other user's calendar. What I've already done is creating a service account and using PowerShell, giving this account create and edit owned items permissions on everyone's calendar so that this service account can create and only edit items that this account has created. This PowerShell script is executed every day to add this permissions to every new user created.

Hope this helps

Hi Caroline,

I have a separate workflow which uses a Create Appointment action to create appointments in individual outlook calendar base on the creator of the appointment and it's attendees. and I only use Web Request action for updating the appointment when it is modified in the sharepoint calendar. Our team has a separate email which all of the technical teams in our company check upon on it's calendar. This team email is also the credential I use on creating appointments on other calendars. Should I just put this credential on the web request? because I don't know what email I will put on the code below:

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">
<soap:Body>
<FindItem Traversal="Shallow" xmlns="http://schemas.microsoft.com/exchange/services/2006/messages">
<ItemShape>
<t:BaseShape>IdOnly</t:BaseShape>
<t:AdditionalProperties>
<t:FieldURI FieldURI="calendar:Start"/>
<t:FieldURI FieldURI="calendar:End"/>
<t:FieldURI FieldURI="item:Subject"/>
</t:AdditionalProperties>
</ItemShape>
<Restriction>
<t:Contains ContainmentMode="Substring" ContainmentComparison="IgnoreCase" >
<t:FieldURI FieldURI="item:Subject" />
<t:Constant Value="Subject to find" />
</t:Contains>
</Restriction>
<ParentFolderIds>
<t:DistinguishedFolderId Id="calendar">
<t:Mailbox>
<t:EmailAddress>test@mail.com</t:EmailAddress> 
</t:Mailbox>
</t:DistinguishedFolderId>
</ParentFolderIds>
</FindItem>
</soap:Body>
</soap:Envelope>

If the team email account has write permission on attendees' calendars then you should put the credentials of this account.

Regarding the email address to put in the XML, part you've written in red, you should put the email of the calendar to update, so the email address of the attendees. You need to perform one request per attendee as the id of the event to update will be different from one calendar to anotther one (one request per attendee to get the id of the event to update and one request per attendee to perform the update of the event).

Hope this helps
