Microsoft’s Outlook cannot send large files.
Like dissertations.
Microsoft help explains that files should have images and pictures removed to be emailed.
They want me to take the figures and pictures out of my dissertation.
Another option would be to use Onedrive, however that never works. Every time I send a large file via Onedrive, there are infinite problems and no one can open it easily.
Microsoft Outlook is not capable of supporting higher education.
