Hi Shaistha,

Thank you for posting the query on Microsoft Community. I am sorry to know that you are facing issues with Outlook.com

  • How are you trying to access Outlook.com?  Is it through Web or App?

  • Is the issue confined with one particular sender/domain or with anyone?

  • Is the attachment size more than 10 Mb?

Please be informed, if you send an email that exceeds the maximum email size limit of the recipient’s email provider, your email will bounce off and you will receive an email error back in your mailbox. Usually, you will receive one of the following error messages:

– “Attachment size exceeds the allowable limit”;

– “552: Message size exceeds maximum permitted”;

– “System Undeliverable, message size exceeds outgoing message size limit”;

– “The size of the message you are trying to send exceeds the global size limit of the server. The message was not sent; reduce the message size and try again”.

Here is the values list of the maximum email size limit for Outlook.com

Email Provider Maximum Email Size Limit
Outlook.com and Hotmail 10Mb (Per file attachment) or 300Gb (only for files attached via OneDrive)

Email Client

Maximum Email Size Limit

Microsoft Outlook 20Mb (per attachment)
Windows Live Mail 10Gb (per email) and no more than 50Mb per file attached

Please get back to us with the above information to assist you accordingly.
