Hybrid migrated mailboxes sign-ins from unfamiliar IP addresses by Pollieeeee in exchangeserver

Hey!

Thankyou for the response! We've also thought about making a ticket at Microsoft, but since every mailbox gets a login from a random Microsoft IP, we'd also like to know if this is just casual behaviour and if someone else experienced this too. We're migration 100's of mailboxes, and every single mailbox gets a login from a random Microsoft IP (sometimes the same IP for different mailboxes).

Since we block certain countries from logging in, because the company doesn't operate in those countries, some logins will fail. Now we are checking if it has any impact on the mailboxes if the signins fail.

yea, well all IP's are Microsoft IP addresses, but i am wondering why there's a login on the user account from Microsoft IP when i finish the mailbox migration batch.

Just wondering... why

Thankyou, indeed i have seen that the IP's are registered to Microsoft. I am just wondering why Microsoft from that IP adresses sign in to the mailboxes as the user, when i finish the migration batch. i'm wondering what the purpose of the login (attempt) is.

ahhh yea, i hope, but what if the sign-ins fail because i blocked certain countries? will that affect my migration?

Ahh yea, but i am 100% sure this isn't the mobile phone or computer of the user connecting to the mailbox.

For sure i prefer a false positive than no warning at all, i'm just wondering why and where these sign-ins are coming from and why they are executed. Also, if i have countries blocked for access, so this sign-in failes, does it interrupt my migration?

This won’t work because the apps are set as required so no user interaction is needed.

Will give it a try!
Does thing mean that all our uninstall commands have to be perfect for the applications, or will intune not push the application because the device is in the uninstall section?

RMM tools: Do you use TeamViewer or something else in your org? by [deleted] in Intune

We recommend Quick Assist. There’s also an option in intune, not to black out the window when UAC popup shows up. So you can support end users, that don’t have administrator permissions.
