Send admin notifications on x number of messages from an email address
Hi, We're having a problem with a repeat spam/phishing offender that recycles email addresses from a particular domain. Because the email address is new it hasn't had a chance to be picked up by blacklists, so it doesn't get picked up as spam. We can't block on content, subject or sender because it all changes so for these campaigns we're relying on user reports to give us the heads up. We also can't block the domain because we receive legitimate email from the domain also. I'd like to change this so we can hit them before users notice and possibly whilst the spam campaign is in flight but I'm unsure as to how to go about it. Is there a rule or other setting I can configure which sends notifications to specific e-mail addresses if, say 100 emails were received from any email address (or from a specific domain?) within an hour, or 5 hours? I don't see how I can configure such a rule in mailflow rules so I'm guessing this might be somewhere else. There's an element of us likely being falsely alerted to marketing campaigns, but hopefully it's configurable enough that we can limit it down to only applying this against a specific sender domain, or adding a new custom mailflow rule which will lower the likelihood of false positives. Many thanks, - Lsward

Gmail to Microsoft 365 Migration Issue Open for 7+ Days – Seeking Guidance or Escalation Path
I’m facing an issue with a Gmail to Microsoft 365 migration that has been open for more than 7 days, and I’m looking for guidance or an escalation path from the community. Scenario: Migration type: Gmail to Microsoft 365 Issue started: April 22 Current status: Stuck with no clear resolution What’s happening: The support ticket has been active since April 22. However, the updates I’ve been receiving are generic responses such as “we are working on it” and “this has been prioritized.” Despite multiple follow-ups, there has been: No clear root cause identified No ETA provided No technical breakdown of the issue I also requested a callback from the assigned manager and technical lead to better understand the situation, but the communication has remained email-only with repeated status updates. What I’m looking for: Has anyone faced similar issues during Gmail → Microsoft 365 migrations? Are there known blockers or common causes that could lead to this kind of delay? What is the recommended escalation path when support is unable to provide technical clarity or ETA? Any insights, workarounds, or guidance would be highly appreciated. Thank you in advance.
Cross Tenant Migration licensing
Hello, I'm planning a native cross-tenant migration for several shared mailboxes that have archives enabled. I’m looking to confirm if it is necessary to temporarily convert these to user mailboxes in the source to ensure the archive data migrates successfully. Also, what specific licenses should I assign to the target objects specifically, do I need to provide an Exchange Online Plan 2 plus the Cross-Tenant User Data Migration add-on for each shared mailbox? If anyone has handled archived shared mailboxes recently, I’d appreciate a quick confirmation on the cleanest licensing and conversion steps. Thank you in advance ! :)Exchange 2016 Decommission
Hi all, I am trying to decom my 2016 environment and cannot disable (Disable-Mailbox) the final 16 mailboxes (out of thousands). Am getting the error Active directory response: 00002098: SecErr: DSID-03150A45, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0. I have been troubleshooting this for HOURS now. It's not enabling inheritance on the user perms (every article suggests that). The perm exchange trusted subsystem isn't there. The users do not have any admin groups. It's nothing that I can find in the first 6 pages of googling. Sadly, of course, there is no support anymore so can't even raise a ticket. Can't uninstall Exchange with mailboxes left :( Any idea's are more than welcome, please. Thank you.
Is the Archive mailbox self-help diagnostic working for anyone?
Just curious: is the archive mailbox self-help diagnostic at https://aka.ms/PillarArchiveMailbox working for anyone? When I run it, instead of getting results about the user whose UPN I entered, I get this: The following issues were found with your archive mailbox. No account was found for [The UPN of my admin account]. Make sure you've entered the correct email address or create a new account with that name. For more information, see Add users to Office 365. I tried opening a ticket with Microsoft Support, but they refused to work on it without requiring me to do all the legwork of gathering logs and HAR traces and who knows what else, despite the fact that the support agent was able to replicate the exact same issue in his lab.

ThanksEmail Showing as Quarantined in a Message Trace, but Not Showing up in MS Defender
A customer of ours was waiting on an email to arrive and to help figure out where the email was or if it was sent yet we ran a message trace. The message trace showed that the email was sent to quarantine. With this information in mind, I went to MS Defender > Email & collaboration > Review > Quarantine but could not find the message. I modified some of the filters and could not get the quarantined message to appear. I triple checked the filters I created and made sure the information was correct. I also removed all filters and looked for the time period the email came in, but could not find it. Not sure if this is related, but this email had a significant delay likely coming from the sender. Any thoughts or ideas? Or anything that I am missing?
Mailbox for Service Account (exchange online)
Hi Our organisation isn't ready to move to Exchange Online yet, though we have Office 365 e3 licencing. I need to create a service account that can send emails via Outlook 365 for use In Power Automate. The documentation I have seen for adding a mailbox to an existing AAD user requires assigning an exchange licence to the account via the licence portal. I can't see any such licences though we do have e3 licencing which are visible that I assume covers this? Unfortunately the admin who did the original configuration has moved on and I don't have a global admin role so have to go through a support team that can't help me with my lack of knowledge in the area! Any advice would be very much appreciated as what ( i think) should be a simple task has taken a lot of time to try and get to the bottom of! Thanks, Dale.
