The maximum size for an email message in Exchange 2020 is 10 MB (megabytes). This is a default setting, but it can be adjusted by the Exchange administrator.

Here are some key points to note about email size limits in Exchange 2020:

  1. Default size limit: The default maximum size for an email message in Exchange 2020 is 10 MB.

  3. Attachment size limit: The maximum size for an email attachment in Exchange 2020 is 3 GB (gigabytes).
  4. Message size limit: The maximum size for an email message, including attachments, is 10 MB.
  5. Large file transfer: If you need to send a file larger than 10 MB, you can use the Large File Transfer feature in Exchange 2020. This feature allows you to send files up to 25 GB in size.
  6. Quota management: Exchange 2020 includes quota management features that allow administrators to set limits on the amount of storage space used by individual mailboxes. This helps prevent users from storing too much data in their mailboxes.
