Re: What to do? SE or Decommission
Depends on the organisation and skills if moving this way will work. If you were looking at a change though, this is the way I would go. It has gone GA. There is another phase of rollout that will introduce write-back. User and groups SOA switch is also available and in Preview (for users anyway).53Views0likes0CommentsRe: What to do? SE or Decommission
There's a 4th option of migrating SMTP to another service and moving SOA for Exchange to the cloud and getting rid of on premises Exchange attribute management altogether. https://learn.microsoft.com/en-us/exchange/hybrid-deployment/enable-exchange-attributes-cloud-management114Views1like2CommentsRe: Policy for limiting external domains and allowing particular external receivers
There's no need to create a mail flow rule at all. Best practice is to create a new outbound anti-spam policy with external forwarding enabled (and all other settings the same as the existingpolicy) and scope it only to the users you want to allow to email forwarding.26Views0likes0CommentsRe: Multi-Tenant Microsoft Exchange Online support
Why would a multi-tenant org be in place here? Just provision accounts in your tenant for the required technicians as required and decom them when they don't need them. Partners can set up what's called Lighthouse, which enables them to access mutliple customer tenants through a single portal, but you have no real control over that, other than authorising the partner access.29Views0likes0CommentsRe: Emails delayed or not received.
If the message left your environment OK, there's not a lot you can do. If you can work with the admins at the recipient company, then you can get them to investigate the message routing and any services that might have quarantined the message on their end and see why (it might require work on their end or work on your end depending on the results). If you can, try get a copy of the message header for a message that was delayed from someone who received it and see what path it took and how long each hop was.34Views0likes0CommentsRe: Why would a hacker/scammer put a domain INTO my exchange online admin?
You can review the Purview Audit search to look for audit logs (as long as auditing was enabled!). I'd be logging a ticket with Microsoft to get the domain removed ASAP. Definitiely a bit of a weird one. I'd say this is a form of Business Email Comprimise and they are trying to trick vendors/partners into sending money their way, but why they would use your tenant is a bit unusual if they could just set up a new tenant and add the domain there. If they were able to register the domain in your teannt, the malicious actors obviously also have access to the other domain's DNS records as well, so that ain't good!! I'd be locking down all the GA/priviledged accounts ASAP. Best practice is to not give user account GA access and make admins use a separate priviledged account to do any admin tasks. This means that if their user account is compromised, at least the bad actor doesn't get admin priviledges in the tenant straight away.54Views0likes1CommentRe: Clarification on Exchange Server SE Edition and Licensing
Your best bet is to talk to your Microsoft licensing partner, but in a nutshell SE requires a server license with Software Assurance for each server and a Client Access License (CAL) for every user or device accessing the server. You can choose between traditional CALs or cloud subscription licenses.181Views1like0CommentsRe: Domain not routing mail or logins correctly after tenant transfer
Google is notoriously slow with updating their MX routing. Are you getting any email from external senders at all? Also check that your device is not still connected/registered/enrolled to your old tenant. Sounds like SSO is kicking in when trying to login to the apps. Try it on a fresh image and/or with a PC enrolled into the new tenant. I'd also suggest that you log a ticket with Microsoft.39Views0likes0CommentsRe: I need help with migration
All that you mention is possible. Becasue you haven't mentioned about either the source or target environments (or even if you in fact need to do a migration or just need to change your primary email address), I'd guess you're not that technical, so I'd recommend looking around for a 3rd party that can help you do the work. Perhaps the buinsess you are merging with has the technical knowledge to help you do the work.50Views0likes0CommentsRe: Moving Exchange Hybrid From Exchange 2016 To Exchange SE
The whole idea for the change is to move mail flow to the new server, so yes it will affect where EXO sends mail. As long as you have your new Exchange server configured correctly, the change shouldn't casue an impact though.177Views0likes0CommentsRe: Moving Exchange Hybrid From Exchange 2016 To Exchange SE
the HCW won't specifically say there are firewall errors. There will just be a connection/network error. DNS will need to be in place before you run the HCW, as it will try and connect using those namespaces when you run it.221Views0likes2CommentsRe: Local domain mailbox migration error
You'll need to remove the .local address from the on-premises email address policy, then run a script to remove the .local addresses from all accounts, then you should be good to go make sure that the UPN and primary email address for all users match and don't use the .local address. the IdFix utility from Microsoft can help you discover what accounts aren't configured correctly57Views0likes0CommentsRe: Local domain mailbox migration error
It's only added by default becasue you have the .local address in your email address policy. Update the email address policy to remove the .local address, then you'll need to run a script to remove the .local address as an alias from all existing accounts (removing the .local address from the address policy will not remove it from existing objects, it just means any new objects will not have the .local address).100Views1like0CommentsRe: Exchange 2016 Maximum number of recipients in a message that's sent by the specific sender
This Microsoft Learn page says: If the mailbox level RecipientLimits is set to unlimited (the default value), then the maximum number of recipients per message for the mailbox is controlled by the Transport level MaxRecipientEnvelopeLimit.74Views1like0CommentsRe: Centralized mail transport and sending outgoing messages directly from EXO
You'll need to create a mail flow rule that is configured to route all mail via a specified connector with the exception of the pilot group of users. Depending on your config, you may also need a new connector for this that's of type "used with mail flow rule." The pilot group will then be routed directly to the internet via the hidden EXO external connector. When you decide to cutover all users, you just disable the mail flow rule, then after a period you can clean up by deleting the rule and connecter pairing.80Views0likes0CommentsRe: How do you handle off-hours patching in small environments with no HA?
Should be the same as any server...monthly patching window after hours as you'll need to factor in both the server level OS patches as well as Exchange patches. Rollback...you'll need to follow the supported options available...although there are a lot of organisations that do use snapshots as a roll back. If you do use snapshots, make sure the snapshot is of an Exchange server that is in maintenance mode.68Views0likes0Comments
