Updated Exchange Online Limits

Microsoft have updated the official Exchange Online Limits service description to reflect the recent changes in message limits, as mentioned in my previous posts; Change in Maximum Message Size limits in Exchange Online and Transcoding Exchange Online Message sizes.

Two important notes:

  • Across all Office 365 plans, the limit for file attachments in OWA is set to 25MB and in Outlook for Mac the limit is 35MB.
  • With Office 365 E1 plans the general file attachment limit is 25MB in the Office Outlook client.
