Scheduling Assistant no longer functional?
I note that I see Microsoft have announced an inncident, however, i'm not completely sure these are related: https://admin.cloud.microsoft/?#/servicehealth/:/alerts/EX1092751 A few weeks ago we had no issues making use of the scheduling assistant feature when inviting users, however, this seems now to have broken. Oddly enough if I was to add one of these users calendars to my own I can still browse them without issue, it's only durig the scheduling function that it is left completely grayed out. On investigation, it appears tied to users setting their working hours, by default this appears turned off for users, but if I was to set this, it does seem to work, albeit after some time waiting. Could this be due to an issue from MS, an unexpected change from MS (Places?) or something else? But it seems it's no longer pull the data from the same location, and as such, we're a bit confused as to why.
Cross forest Distribution Group list expansion
We have two forests in a 2-way trust. On each forest there's an Exchange 2016 Organization installed. On one forest a Distribution group has been created with users from both the forests, in ADUC we see the membership correctly for all the users. On the Exchange Console of that Forest opening the DG we can see only the "local" users and the SID for the remote one. Sending an email to the DG it only delivers to local forest's users. Why Exchange Server doesn't expand the DG membership as the ADUC does and deliver emails to all recipient ? Do we have to replicate remote Forest's Users as local contacts ? thanks
How to Delete a Composing Email Attachment via Outlook Add-in?
Context: Server: Exchange Server 2019 on premise Client: OWA Category: Outlook Add-in Office JS API Set: Supported up to 1.5 only Problem Details: Delete an attachment added manually or through EWS API to an email item. Limitations: 1. Limitation of makeEWSRequestAsync() Office JS method: The makeEWSRequestAsync method in Office.js does not support the DeleteAttachment SOAP operation, which is required from outlook add in. -> Attempted Workaround - Using fetch with EWS SOAP Request: I tried invoking the DeleteAttachment operation via a fetch call to the EWS endpoint. However, EWS response states "requested web method is not allowed for this application". 2. OWA Limitation: As OWA in this environment only supports Office.js up to version 1.5, the modern attachment Office JS APIs and Graph APIs are not an option. Question: In an Exchange On-Premises scenario, how can I programmatically delete attachments via my add-in? Specifically, is there a recommended approach to obtain a valid token for EWS requests, or any supported alternative to perform DeleteAttachment? Any way to convert EWS attachment ID to Office JS attachment UUID? Additional Notes: I am aware that Exchange Online supports more modern APIs (Graph/REST), but my current deployment is strictly Exchange On-Premises. The add-in works well for reading attachments and other operations, except for deletion. Any guidance or recommendations would be highly appreciated! Thank you in advance.
SMTP relay without on-prem Exchange server
Hi Exchange Experts, One of my Customer has following Requirement: They have already migrated all their user mailboxes to Exchange Online. They still have 2 Exchange on prem servers functioning as SMTP relay for their applications and printers. They want to decommission the 2 Exch servers and directly use Exchange online (yourdomain-com.mail.protection.outlook.com) as SMTP relay. Their applications and printers do not have a public ip address. They don't want to use any on-prem mail relay servers. They don't want to use azure Communication Services. Their devices and applications do not support TLS 1.3 or TLS 1.2 What would be the best solution ? Thanks and Best Regards, Vijay.If Basic SMTP Auth will be disabled in Sept. 2025, how does one send SQL Server Database Mail?
According to this article: Exchange Online to retire Basic auth for Client Submission (SMTP AUTH) | Microsoft Community Hub, basic SMTP Auth will be disabled in Sept. 2025. I know it was already disabled previously but we were able to create an authentication policy to allow it. This sounds like it will be permanently disabled come September. In SQL Server, we have database mail configured to send mail using Basic Authentication. Windows Auth and Anonymous auth do not work. How will this work come September?
Organization Sharing with Google Workspace
Hello all, In Exchange it is possible to share organization calendars with other organizations, when these companies use Exchange. When we add a domain that is hosted in Google Workspace, we get an error. Is it possible to configure Exchange/Google Workspace so we can share calendars? Kind regards, ArjanNeed expertise advise on an event of mass mail-send
Hi all, We have a consultation from one of the application team about a mass mail that they are planning to send the number of emails is 60k, the challenge here is we cannot ask them to create group and send out an email because each of the recipient will be sent with a distinctive attachment and distinctive mail body content, hence no solution will work for now. We have a hybrid exchange setup with an Open SMTP Relay that connects to around 32 Exchange onprem servers and these servers will route those mails to Office365 Exchange Online as all of our mailboxes are hosted in Exchange Online. ALthough i am suggesting them to break these down to smaller batches and send in different time-slots giving 30 minute gap after each gap. I just want to be thoughtful and give the best suggestion, so what are all the things i would need to look into from Exchange standpoint and end to end monitor the situation.
