External forwarding from Office 365 Exchange mailbox stops working

Issue

Emails forwarded to external addresses from MS Office 365 Exchange mailboxes no longer get forwarded. Instead, the following bounce message goes back to users' mailbox:

Delivery has failed to these recipients or groups:
Name (email)
Your message wasn't delivered because the recipient's email provider rejected it.

Preview all segments on Strava route before a ride

When you create a new route on Strava (web version) it does display some more popular segments on the route preview page. But the full list of segments is only visible when the route is completed and uploaded as a ride. Here is a little workaround to check all segments on a route before riding:

Office 365 - You can't assign licenses that contain these conflicting services...

Issue

Trying to increase user's Office 365 mailbox size by assigning Exchange 2 license. The user already has Office 365 Business Premium (Microsoft 365 Business Standard) license. The operation fails with the following error:

You can't assign licenses that contain these conflicting services: Exchange Online (Plan 1),
Exchange Online (Plan 2). Review the services included with each license, and try again.

Office 365 - cannot delete shared mailbox alias

Issue

Microsoft Office 365 shared mailbox secondary alias cannot be removed. I tried removing the alias via Office 365 Admin Center, Exchange Admin Center, and PowerShell (Set-Mailbox "mailbox.name" -EmailAddresses @{remove="This email address is being protected from spambots. You need JavaScript enabled to view it.;}). None of these methods works, it initially looks like the operation succeeds, but the alias is never removed.

The shared mailbox in question used to be a user's mailbox, and the alias in question used to be the user's primary email address. I also tried changing the mailbox username / login name, and email alias, but this didn't help either.
