Can’t see that this is a problem anyone has asked about already but all of us at my work have the following issue in Outlook:
When we get an email notification of for example someone has commented on an item the message box area of the email with the text is a monumentous scroll way down the email through a large grey area.
have you tried to reupload the company-logo in admin-settings of Monday?
Looks like there is an error with header settings. Be sure to have correct picture solution(s).
