<\/figure>\n\n\n\nIf you try to send a file larger than 20 MB in Outlook, you\u2019ll get a message similar to \u201cThe attachment size exceeds the allowable limit.\u201d <\/strong>Another variation of this error is \u201cThe file you\u2019re attaching is bigger than the server allows.\u201d<\/strong><\/p>\n\n\n\n If you\u2019re in this situation, there are several ways to tackle this \nissue. One way to mitigate the problem is to upload large attachments on\n cloud drives and only send the link to the recipient through an email. \nCloud servers will allow you to upload files as large as 15 GB free of \ncost.<\/p>\n\n\n\n Another, more elegant solution would be to increase the default \nattachment limit in Outlook to match the email server\u2019s default size. \nFor Gmail and a few other email providers it won\u2019t be a huge \nimprovement, but if you use a self-hosted email server or Exchange, you \ncan go way higher.<\/p>\n\n\n\n Below you have a collection of methods that will allow you to send larger files through Outlook. Take a look!<\/p>\n\n\n\n The guide below will show you how to edit the registry so that your \nOutlook will allow larger attachments limits. We are going to modify the\n parameter of MaximumAttachmentSize<\/strong> using the Registry Editor<\/strong>. Here\u2019s what you need to do:<\/p>\n\n\n\n Now check the Decimal<\/strong> option and enter the attachment size limitation in the Value data<\/strong> box. The size limit needs to be added in kilobytes. For example, if you want to set the size limit to 25 MB<\/strong>, you need to enter 25600<\/strong>. It\u2019s good practice to reduce the Outlook limit to allow some wiggle room of at least 500 KB.<\/p>\n\n\n\n Note:<\/strong> If you\u2019re using Exchange<\/strong>, be advised not to set the MaximumAttachmentSize<\/strong>\n higher than the account is allowed. If you fail to do so, the message \nwill not send. Even more, do not leave the file size limit to 0 as it \nwill render all your emails undeliverable.\nPress Ok<\/strong> and close the registry editor.\nTry sending an email through Outlook with an attachment larger than the size previously allowed.\n\n<\/p>\n","protected":false},"excerpt":{"rendered":" Most email service providers limit the maximum email size that can be sent or received by an account. But it\u2019s actually a necessary restriction \u2013 otherwise, emails can be easily exploited by being flooded with very large emails. If you try to send an email that exceeds the maximum limit of the recipient, it will bounce off and you\u2019ll receive an error<\/p>\n![\"\"](\"http:\/\/tamer-az.com\/wp-content\/uploads\/2018\/11\/outlook-error-2.png\")
