Questions[microsoft-365](server)

In a Windows Domain with Microsoft 365 when a user has used more than 20 devices they get an error they have have to unregister in order to sign into a new Windows 10 workstation. Does anyone know of a way to unregister devices that are found on the page https://myaccount.microsoft.com/device-list from powershell for users?

Here is the help guide for the page so you can see the page I am talking about: https://support.microsoft.com/en-us/account-billing/manage-your-work-or-school-account-connected-devices-from-the-devices-page-6b5a735d-0a7f-4e94-8cfd-f5da6bc13d4e

Company I work for has two domain names and they created two different tenant accounts for each domain. this makes it hard to collaborate.

I need to migrate contoso.com from a tenant account to a the other one. Can any one suggest a way to this please? contoso.com users only have emails and onedrive content. there is no teams or sharepoint online content to migrate.

Thank you.

I have set up some phishing/malware mail-flow rules that will forward emails to me for review based on attachments or a list of domains. I can then choose to accept or reject the message. It seems to work well. The problem I'm having is that this weekend, some were automatically rejected because I didn't respond in time.

How do I change this time to "auto reject"?

I'm viewing a message trace from https://admin.exchange.microsoft.com/#/messagetrace

If I expand "More Information" on the selected email, I see "Message id". When I go to https://security.microsoft.com/reportsubmission and try to submit it, it asks for a "Network Message ID". I tried entering the "Message id" from above, but it says it's invalid. I can't find "Network Message ID" (or any other ID) anywhere in the trace. What am I missing?

How do I submit a message to Microsoft?

I have an office365 account and cannot link my email to my email client. I have MFA activated and the only client that allows me to link the mail is the same Outlook 2019 for PC or Mac.

Can I link you with other clients or mail managers? I have followed this guide. How do I setup O365 to allow IMAP?

I have IMAP enabled I have application passwords I have the correct servers, IMAP and SMTP

I was finding out and I think there is something more to do.

Does anyone know how to allow linking office365 with any mail client in IMAP?
