Outlook - max. mb on attachments

Question

What is Outlook's maximum mb attachment allowed for each email to be sent, without reducing size for viewing?

Answer 1

In Outlook, the maximum attachment size allowed for each email depends on the type of email account you are using:

• For Internet email accounts (like POP3, IMAP, HTTP), the default attachment size limit is 20 megabytes (MB).
• For Microsoft Exchange Server email accounts, the default limit is 10 MB for the total size of all attachments.
• For Exchange Online, the maximum file attachment size limit is 150 MB for Outlook, while it is 112 MB for Outlook on the web (OWA).

These limits are in place to ensure that emails can be sent efficiently without exceeding the constraints set by email servers and providers.
