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.Exchange Online to Deprecate Legacy TLS for POP3 and IMAP4
Microsoft will start to refuse inbound IMAP4 and POP3 client connections using legacy TLS versions (1.0 and 1.1) in July 2026. The move is consistent with other projects to remove obsolete or insecure email protocols from Exchange Online to increase the overall security of the online email service. In this article, we examine some methods to understand the POP3 and IMAP4 usage within a tenant. https://office365itpros.com/2026/04/29/legacy-tls-removal/
Permission activesync on smartphone
Hi everyone, when you grant the permissions in question to manage company email from a smartphone, do these permissions, in addition to Remote Wipe, Password Enforcement and Device Encryption (I remember these as the main ones), somehow give the Exchange administrator access to my personal data? For example, photos, any documents saved on the SD card or on the smartphone itself? Thanks in advanced!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
