The Final Countdown to Remove EWS from Exchange Online Begins
Microsoft announced the dates leading to the final retirement of Exchange Web Services from Exchange Online. If all goes well, the EWS retirement in the cloud will happen by May 2027. Challenges still exist. Microsoft must remove EWS from its own apps, including Outlook, and help tenants and ISVs make the leap to Graph APIs. Plans are in place and progress is being made, but will everyone be ready when Microsoft starts to remove EWS permanently from Exchange Online in April 2027? https://office365itpros.com/2026/02/06/ews-retirement-may-2027/
Retrieve folder favorites with EWS
Not sure if this is the correct place to ask, the old Exchange Development Forum is no longer available. We are trying to retrieve favorite folders (shown in Outlook as "Favorites") with EWS. To do that we open the associated items of the "common views" folder. Using MFCMapi and EWSEditor we have identified/guessed the PidTagWlinkSection flag to indicate an active favorite if it has the value 1. We do not know how to retrieve the folder that has to be associated with this favorite though. Any tips how we could identify this? GlenScales
Trouble Renewing self-signed Exchange 2019 certificate
I have an Exchange 2019 CU14 server whose self-signed certificate (for IIS and SMTP) has expired. I used the Get-ExchangeCertificate cmdlet to find the thumbprint for the expired certificate. However, when I use example from this page: https://learn.microsoft.com/en-us/exchange/architecture/client-access/renew-certificates?view=exchserver-2019 to renew the certificate it does not work. Can anyone help me to solve this issue? Thank you. The cmdlet and the response is listed below. Get-ExchangeCertificate -Thumbprint 64AB20ED34134811522D298904D135A25E6A86BD | New-ExchangeCertificate -Force -PrivateKeyExportable $true The input object cannot be bound to any parameters for the command either because the command does not take pipeline input or the input and its properties do not match any of the parameters that take pipeline input. + CategoryInfo : InvalidArgument: ([Subject] CN...135A25E6A86BD :PSObject) [New-ExchangeCertificate], ParameterBindingException + FullyQualifiedErrorId : InputObjectNotBound,New-ExchangeCertificate + PSComputerName : mail1..com
EWS Connection is not working anymore
Hello all, we're using the OnTime Group calender https://ontimesuite.com/resources/microsoft/documentation/ for additional functions for Exchange Online. This solutions worked for the last months. Starting with Tuesday 05th December this tool stopped working because the user synchronisation via EWS is not working anymore. The tools connects via an Enterprise Application and an Impersination user. We get following EWS Respsone when trying to sync a Microsoft 365 group or a distribution list: EwsResponse http://schemas.xmlsoap.org/soap/envelope/">http://schemas.microsoft.com/exchange/services/2006/types" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">No results were found.ErrorNameResolutionNoResults0 I tested the same scenario with the OnTime Server with a developer tenant and there it works. We also tried to resolve Distribution lists via EWS Editor it works well in the Dev Tenant but not in our Prod Tenant.. Do you have any idea why the Nameresolution isn't working anymore? What can we check? Thank you very muchMicrosoft Signals the End for Exchange Web Services
On September 19, 2023 Microsoft announced their intention to retire the Exchange Web Services API on 1 October 2026. The suggested replacement is the Microsoft Graph API. Microsoft acknowledges that some gaps exist that they need to close before EWS retirement happens, but one big issue they didn’t discuss is what happens to the backup products that currently use EWS to backup Exchange Online. https://office365itpros.com/2023/09/20/exchange-web-services-retire/
