Address rewrite not working for Calendar items
Hi, We are running a hybrid environment with 3 active directory domains, 3 on-prem Exchange clusters and the majority of our mailboxes in O365. We have set up a default address rewrite so that emails from everyone across the 3 different legacy domain names appear to come from the new domain name. Emails are sent from O365 back to the on-prem clusters for rewriting. Lets use an example john@oldcompany1.com john@oldcompany2.com john@oldcompany3.com Address rewrite is set up so all emails from the above addresses are displayed to external recipients as: john@newcompanyname.com This works perfectly for all outbound emails, however it does not work with meeting/calendar invites. For example, my own mailbox has the default alias of @oldcompany1.com, and when I send an email to a recipient outside of our organisation, it shows as coming from @newcompanyname.com, but when I send a meeting/appointment to an external recipient, it shows as coming from @oldcompany1.com. Has anyone seen this before, if so - do you have any tips on where to start the troubleshooting process?M365 License Expiration- Enterprise Agreement
Scenario: I have 3050 M365 E1 plan license and going to expire soon. My Org planned to renew 1250 M365 E1 plan. As i have Exchange Hybrid environment we have plan to migrate 1800 user mailbox to exchange servers. As limited time, we may not complete all migration so what will happen to after the license expiration date? Does migration in-progress will stop or run until process complete? Does License will promptly remove from License portal or will stay for grace period?And if license not remove from portal, does user can login and use exchange online services? Please suggest??
O365 Online Archiving Not Working
We migrated users to O365 last week. And for the most part everything is good. All using E3 licenses But one users mailbox is not archiving. I've confirmed that is OWA for the user right clicked on user name and Assigned Policy is what we configured right clicked on folders and they are set to use parent Can see the in-place archive folder but nothing is in it From Powershell Get-mailbox user | RetentionPolicy Set, ArchiveDatabase Set, ArchiveGuid set Run Start-ManagedFolderAssistant a few times From Security and Compliance Archive enabled But still nothing is moving to the archiveMigration from hybrid active directory & hybrid exchange to cloud-only environment
Is it generally possible to migrate fromhybrid active directory & hybrid exchange to a cloud-only environment with Entra ID and Exchange online & NO additional virtual machine in Azure? One service provider advised against this and said that once a hybrid environment exists, it must be maintained forever. Background: we want to shut down our data center and outsource everything to the cloudMigrating On-Prem Distribution Groups to Exchange Online in Hybrid Mode
I have come across a number of articles on migrating distribution groups to Office 365 when you're not in hybrid mode. My situation is having hundreds of DLs on my on-prem Exchange environment that I need to move to the cloud. We don't want these converted to Office 365 groups, we want true distribution groups in the cloud. Is this possible with scripting or some other method? I really don't want to have to re-create these by hand.
Distribution Group Migration Script
Hey Guys, We're in the process of migrating our distribution groups to Office 365. We already have them sync'd to the cloud but have decided (for a number of reasons) to simply migrate them to the cloud completely. (mastered on office 365) We're breaking this into 2 parts: Migrate Non-Nested Groups, Migrate Nested Groups. My question really applies to both. I found this script here:https://gallery.technet.microsoft.com/office/PowerShell-Script-to-Move-5c3cd668its an old script but definitely works. The script works this way: Copies all settings of a group you specify to a temp group (creates a temp group) you then remove the group from AD Connect run the sync process You then finalize the group, which means it basically takes the "temp" group and renames it to the original name of the group. The only question I have is this, when the script renames the temp group to the perm group, it prepends the SamAccountName with Cloud- for every group it migrates. Do you think that will be an issue? It does not affect anything that I can find, I realize if this were an all onprem environment, then it could very well be an issue. But since this is the cloud, i am not 100%. Thanks, Robert
MS365 tenancy security health check suggestions
Are there any useful key controls checklists that could be used as a template to run some checks over an office 365 business tenancy (including Azure AD), to look for common security & access related misconfigurations and risks. Or any tools that will scan current settings, permissions etc and report back with recommendations for improvements and where things could be tightened up? I was hoping for something like the 'top 10' common areas that systems admins could potentially get things wrong with risk implications (e.g. could result in unauthorised access to corporate data), to check we haven’t made the same mistakes, or if we have that we promptly address them.
