由 人盡茶涼 提交于 2019-12-04 09:46:21
I have attempted this with not much success. Basically I need to login to Exchange using EWS remotely.

问题 I am trying to draw a graph of which Exchange User has which permissions on which Exchange mailboxes, coloring them according to the type of permission. As of now, I cannot find out all types of permissions that Exchange takes into account. I can, using EWS, find out who was granted access to a mailbox by the user himself: foreach(var permission in calendarFolder.Permissions) { // do sth. } But then there is the possibility that an admin grants someone permission over a mailbox by adding him

问题 I've seen this question asked several times on the web, but cannot find an answer.

When I update the meeting, the new invitation emails show the time in the UTC time zone. It is the correct time for UTC, but should display in Pacific. I have tried setting the zone when creating the service connection, but this makes the initial invitation also show the time zone as UTC,

I am using EWS 1.2 to send appointments. On creating new Appointments, TimeZone is showing properly on notification mail, but on updating the same appointment, it's TimeZone reset to UTC. Could anyone help me to fix this issue? Here is sample code to replicate the issue: ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP1, TimeZoneInfo.FindSystemTimeZoneById("Eastern Standard Time")); service.Credentials = new WebCredentials("ews_calendar", PASSWORD, "acme"); service.Url = new Uri("https://acme.com/EWS/Exchange.asmx"); Appointment newAppointment = new Appointment
