I am trying to access user's mailbox as well as archive mailbox using Outlook MAPI. Outlook version is 2013. User's mailbox and archive both are in O365 (Exchange Online)
I am able to access users mailbox. However, access to users archive mailbox fails.
I have user's email address and Archive GUID of the archive mailstore.
Can someone please help me understand how to pass Archive GUID of user's mailbox to IMAPISession:OpenMsgStore.
Thanks,
Pranay
You will need to retrieve the legacy DN and server information from the autodiscover XML (Type == Archive), then construct the store entry id using IExchangeManageStore::CreateStoreEntryID in the same fashion as when opening a delegate mailbox.

An administrator for a Microsoft 365 domain can create external contacts that are visible to users within that domain. Those contacts can be seen in the M365 Outlook client under "Directory->All Contacts" or "Directory->Default Global Address list".
I need to use EWS to read and create these contacts. As a first step I'm just trying to read them, using FindFolder, against MsgFolderRoot of a user. Unfortunately the only contact folders that show up are the ones defined for the user in question, not the external contacts created by the Admin. There are several contact folder classes that seem promising, such as "OrganizationalContacts" and "ExternalContacts" but there are no entries in those folders.
I could also use Graph for this if the capability is there. Any help on this problem would be appreciated.
Directory contacts exist in the Directory eg Azure AD or the local AD onPrem neither EWS or Graph can create these type of contacts then only thing automatable that can do that is https://learn.microsoft.com/en-us/powershell/module/exchange/new-mailcontact?view=exchange-ps
For reading Directory contacts the Graph is a better option it has a supportable endpoint via https://learn.microsoft.com/en-us/graph/api/resources/orgcontact?view=graph-rest-1.0. EWS can do this via FindPeople but it's not documented and requires that you know the addressbook guid which isn't available via EWS.
I am running into an issue with Microsoft Flow to create appointments on another calendar that my account as Send As permission to. I am able to create appointments in the UI for this second account. However in Flow, it is asking for a CalendarID. The drop down only shows calendars directly related to the account in the connection. When I manually enter the CalendarID to the second account, I receive this error: "The specified object was not found in the store."
Any help / tutorials will be greatly appreciated.
"The specified object was not found in the store."
This is an EWS permissions error so whatever you doing isn't going to work with SendAS rights. You will need to assign full access permission to the Mailbox (or at least rights to the calendar folder via Add-MailboxFolderPermission) for this to work with EWS. SendAs permission by definition only gives a user rights to SendAS another user not access folders in their Mailbox. You can test all this with the EWSEditor https://ewseditor.codeplex.com/ which is going to be making the same calls. If it works in the EWSEditor with the same creds as flow but not in your other code then you know the rights are good but whatever you doing in Flow is the issue.
I have a service account that I want to be able to access another users calendar through the ews api in such a way that it can create appointments, update appointments they have created and delete appointments they have created but NOT be able to read all items on the users calendar.
This appears to be possible in office 365 (see screenshot) but is it possible with Exchange 2010? If so how?
Sure the image you have posted is just the Folder permissions from Outlook these permission are the same from Exchange 2007 to Office365. The two ways you can set permission pro-grammatically like you have shown is first use one of the Mailbox Access API's like Mapi or EWS and set the Folder permission eg https://msdn.microsoft.com/en-us/library/office/dn641962(v=exchg.150).aspx
Or you can use the Exchange Management Shell and Add-MailboxFolderPermissions https://blogs.technet.microsoft.com/ilvancri/2009/11/24/exchange-2010-and-then-there-is-the-long-awaited-cmdlet-add-mailboxfolderpermission/ this can be a better approach as it just requires delegated admin rights via an RBAC role where setting the folder permission via EWS because it uses a User API would require the account setting those permissions to be the Mailbox owner, have been delegate Full Access rights on the Mailbox (eg add-mailboxpermission) or use Impersonation.
I am using the RDOSession.LogonExchangeMailbox method from the Outlook Redemption library to log into a specific mailbox on exchange server that the current user has access to but that does not necessarily belong to the current user.
If the current user has access to multiple mailboxes, does this method guarantee that only the specified mailbox will be included in RDOSession.Stores? Or is there a chance that other mailboxes (that the user has access to, or even the mailbox for the user himself) will be populated as stores inside RDOSession.Stores?
In summary, can I guarantee that RDOSession.Stores[1] will always point to the mailbox specified in the LogonExchangeMailbox method?
LogonExchangeMailbox (Exchange 2010 or older) always creates a temporary profile that points to the specified mailbox. It is not however guaranteed that RDOSession.Stores[1] will point to the primary mailbox - you can also have a PF store in the profile and the order is undetermined. Use RDOSession.Stores.DefaultStore instead.
We have users in our company that have smart phones (Android/Windows Phone mix)and put their contacts in their Exchange account. It is a unified group of users that just need the phone numbers for each other (with a considerably high turnaround for employees in this position as well). I am looking to get a list of contact names/phone numbers to be automatically pushed to (and updated, if possible) their Exchange contact lists. Previously we have been logging in with their account into a computer, opening Outlook, then loading a csv with the contacts on there. The issue is how time consuming it is, given that amount of turnaround on those users. Thanks in advance!
To create a Contact in a users Mailbox you will need access to that contacts folder in that mailbox so you either need to create a Service Account and give that account rights to the folder via something like Add-MailboxFolderPermission or get the user to delegate the access themselves if they are sensitive to security changes or use EWS impersonation.
Once you have rights to the users Contacts folder then you could automate the process of the CSV import using EWS and Powershell here are a few sample scripts
