Outlook Search Folder for External Senders
I'm using the Outlook M365 desktop app on the current channel and Exchnage 2019 in Hybrid mode with Exchange Online. We route all mail inbound and outbound via Exchange Server. I'd like to create a search folder in Outlook to show only mails from external senders. The issue is the only criteria I can seem to create would rely on the From field and this seems to map to the SenderName on the MailItem object in Outlook. This is not the actual sender's mail address that would include the @domain etc but rather seems to be the senders name which is arbitrary from I can see e.g SomeSender. How to create a search folder based on the senders actual address?
Exchange Online calendar sync tool
We have developed software that synchronizes Exchange calendars. For the past few months, we have been facing a new problem that we did not have before. We synchronize calendar entries based on the LastModifiedDateTime attribute of the Microsoft.Graph.Event class. We are puzzled by the fact that this attribute magically changes without any adjustments on our part. Do you have any advice on this?

We use basic public folder calendars for a number of things. These were originally hosted on on-prem Exchange, and are now on Exchange Online. I normally create them in Outlook, and select 'calendar items' from the list of types. However, I'm currently testing New Outlook, and that doesn't appear to have any ability to create public folders (you can only add existing ones to the favourites list). So I've looked in Exchange Online, and although that can create public folders, it seems to only create basic empty public folders, with no ability to select calendar items to make a calender. Am I missing something obvious, or is it actually impossible to create public folder calendars if using a New Outlook / Exchange Online setup? Thanks
After Exc 2019 Cu15 update Outlook problem
After the Exchange 2019 CU15 update, Outlook 2016 or Outlook 2021 keeps asking for a password. When I check the operating systems, I see that they are versions up to Windows 10 Pro 1607 and 22H2. I wonder if there is a feature that affects older operating systems? Do you have any ideas?How to clear the Discovery Holds folder
To find whether this discovery holds folder is completely full, use the below-mentioned command. Step 1: Connect-ExchangeOnline and then, Step 2: Get-MailboxFolderStatistics -Identity user | select name,foldersize Note: This DiscoveryHolds folder is having a limit of 100 GB. If it is full, we will get issues like "Unable to clear deleted items folder", "deleted items are getting auto-restored" etc., One of the reasons for this folder is full: If Organization Hold is turned on(All Exchange mailboxes are selected in Compliance Retention Policy) or the Individual ID is selected on Compliance Retention Policy. Solution: Please try the below-mentioned steps to overcome this issue. Step 1: Exclude the DiscoveryHolds full ID in the Compliance Retention policy or run the below-mentioned commands in PowerShell. Connect-IPPSSession and then, Set-RetentionCompliancePolicy -Identity "Compliance Retention Policy Name" -AddExchangeLocationException user for multiple users, Set-RetentionCompliancePolicy -Identity "Compliance Retention Policy Name" -AddExchangeLocationException user1, user2, user3 Now on PowerShell, Connect-ExchangeOnline and then, Set-Mailbox -Identity user -RetainDeletedItemsFor 0 and then run the below-mentioned command two times. Start-Managedfolderassistant -Identity user Start-Managedfolderassistant -Identity user After 2-3 minutes, run the below-mentioned commands. Get-Mailbox "user" | FL DelayHoldApplied,DelayReleaseHoldApplied If the output is received as true for any above-mentioned holds, then run the below-mentioned commands. Set-Mailbox user -RemoveDelayHoldApplied Set-Mailbox user -RemoveDelayReleaseHoldApplied and then run the below-mentioned command two times. Start-Managedfolderassistant -Identity user Start-Managedfolderassistant -Identity user After 2-3 minutes, this DiscoveryHolds folder will become zero as per the below-mentioned screenshot. This process helped me a lot. If you have any doubts/concerns/suggestions about this post, please comment below. Best Regards, Venkat Kiran Kona.
Aliasses not showing up in Outlook (classic)
Hello, We have a little issue with aliasses that are configured for some users. New configured aliasses are not shown in Outlook (classic); aliasses that are added in the past are visible. When I use OWA, the new alias is also visible. And also in the offline addressbook the properties are up to date. How can I trigger Outlook to synchronize the new added aliasses? Kind regards, Arjan

Hello everyone, unfortunately, I am unable to add my Ionos (Exchange 2019) email account to the Outlook Windows app. On Windows 10, it was still possible to manually configure an Outlook account, which worked fine. However, on Windows 11, this option is no longer available, and I can’t revert to the previous version of Outlook either. When I try to add the account by selecting Microsoft 365 - Office 365, Exchange and entering my email address, I always get the error message: We couldn't find a work or school account with that email address. I have already contacted Ionos, but they couldn’t solve the issue either. They mentioned that Microsoft doesn’t allow setting up an Exchange account this way, even though the option is listed in the selection menu. Does anyone know how to fix that? Thank you very much!Configure autoreply with rules via PowerShell
Hello, I need a solution where I can set the autoreply agent in outlook with a rule via powershell. I am using exchange online. In the outlook client on my laptop I can activate the autoreply agent and then set additional rules like in my screenshot. However I can´t find a way to do exactly that with powershell. The only thing I can find is that I can activate the autoreply but without rules using Set-MailboxAutoReplyConfiguration. But this CMDlet does not provide options for setting rules for the autoreply agent. Why I need rules for autoreply?....well, I don´t want to forward maiosl marked as private, personal or companyconfidential. Does anybody know a way to creat autoreply with such rules by powershell? Cheers Andre
