Has anyone had issues with Outlook shared mailboxes being renamed to M-files?

We use M-files desktop client and we use Outlook classic client.  Our Outlook classic desktop has the M-files add-in.  Many of our users have several shared mailboxes mapped via Account Settings to open in their Outlook.  Periodically a shared mailbox will get renamed to be "M-files" but still points to a shared mailbox.  Users have to remove this mailbox via Account Settings, and then add it back again.  This fix will work for a period of time, but then it will happen again, with either the same or a different shared mailbox randomly getting renamed.  I opened a support ticket but support was unable to determine the cause.  Has anyone else seen this happen or know how we might prevent it?
