In PHP-EWS library ( https://github.com/jamesiarmes/php-ews ) I can access the calendar events of a specific user using this code: https://github.com/jamesiarmes/php-ews/wiki/Calendar:-Get-List-(Retrieving-Id-and-ChangeKey) In all the library features we always use the authentication for a single user: $ews = new ExchangeWebServices($host, $username, $password, $version); However how can I get the calendar events from another user's mailbox? If I have an account in LDAP with admin privileges is it possible to access the calendar events from another user mailbox using the PHP-EWS library? Or is

Is it possible to tell either in the XML file or through OfficeJs if the add-in can use the REST API or if it needs to use the older EWS API? We have an Outlook add-in that needs to support OWA/O365 and Outlook 2016 with a stand alone exchange server. We are wondering if it is possible through the manifest XML file or through OfficeJs to detect the configuration of users account so we can properly access their content with the correct API. The only alternative I can see is to provide two separate add-ins for this, but I assume MS has a solution to this issue. There isn't a specific API for

The Exchange Web Services have a method GetUserConfiguration that needs a UserConfigurationName to determine what settings to retrieve for a folder. What UserConfigurationNames are available? (specifically for DistinguishedFolderId 'calendar', but a broader list is fine of course). In a distant past I managed to find 4 but I have no idea where I got those and if this is the entire list. It probably depends on Exchange version as well (these 4 work under 2010). These are the four I have come up with, in an example SOAP call: <soap:Body> <mes:GetUserConfiguration> <mes:UserConfigurationName Name

I am trying to get the real email address of the sender of an email using Exchange web services, however the mailitem.Sender.Address contains something like - /O=EXCHANGELABS/OU=EXCHANGE ADMINISTRATIVE GROUP (...........)/CN=RECIPIENTS/CN=...........-..... How can I get to the real email address of the sender of this email? My code: Dim sf As SearchFilter = New SearchFilter.SearchFilterCollection(LogicalOperator.And, New SearchFilter.IsEqualTo(EmailMessageSchema.IsRead, False)) Dim findResults As FindItemsResults(Of Item) = service.FindItems(WellKnownFolderName.Inbox, sf, New ItemView(128))

I am running into a very strange issue and I am convinced it is just something stupid that I am overlooking. Using the EWS managed API, I try to connect to a mailbox to read the contacts. Originally, I used the default credentials, in which case the auto discovery worked. The problem is that later on we want to run this on a server and impersonate a user, so I changed it by manually specifying the credentials. This then broke, even when using my own credentials. As an example, this worked: service = new ExchangeService(ExchangeVersion.Exchange2007_SP1); service.AutodiscoverUrl("user@example
