I have two email accounts in my Outlook for Mac (Version 16.56). One of them allows me to attach documents without any trouble. The other, however, started giving me the following error message about 2 months ago: "One or more files could not be attached because they exceed the file size limit. Total size of attachments must be less than 0MB." I have asked my network administrator about how to increase the attachment size cap in Outlook for Mac, and I have been told that tech support is not available for this problem because even though this account is my work email, I am accessing it on my personal computer (all office computers are PCs; my personal computer is a Mac). How can I increase the attachment size cap in Outlook for Mac? I am running Monterey 12.0.1.
