The total attachment size exceeds the 25MB limit

I have a MacBook Pro using Outlook 2016 for Mac. I get this message when i try to send an email with an attachment larger than 25MB. Any thoughts. Trying to get versions of MAC OSX and Office for MAC. Will update when i receive those version numbers.


Thanks

iMac, OS X Yosemite (10.10.4)

No this is not the answer. The email is hosted in house and being sent within the office. There is no limit to the size that the in house email server will send or receive. It was working last month. And every other MacBook in the office doesn't have this issue.

Here is the proper answer to this problem. My Macbook Pro had Office 2016 for MAC version 15.25 installed and i set my updates to manual and was able to send 27MB attachment. The other Macbook Pro had Office 2016 for MAC version 15.33 updates set to auto. I updated both to Office 2016 for MAC to 15.36 the latest neither could send attachments larger than 25MB. I uninstalled my Office and reinstalled to version 15.25 and can once again send attachments larger than 25MB. This had nothing to do with my mail server or the ISP since the the email wasn't even released from Outlook. Thanks for everyone's time.

That is why I referred you to Microsoft to see if it was a setting in Outlook. It may also be something that you can adjust if you check with them, since all it seems is that you removed an update to Office that made the change. I suspect that Microsoft should be able to answer that question, unless you can see information about what the incremental updates to your Office 2016 would have done to adjust Outlook.


I was able to check my Outlook 2016 on my Windows laptop, and got this from Help. Does not seem there is a workaround other than that mentioned, and what you did with installing different versions, but it seems there is a 20MB limit at this point.


Send large files with Outlook

You’ll receive an error message if you attempt to attach files larger than the maximum size limit. There are a few ways to work around this size limit, including using a file sharing service or compressing the file.

Outlook limits the size of files you can send. This limit prevents your computer from continually trying to upload very large attachments that exceed the limits of most Internet service providers. For Internet email account. such as Outlook.com or Gmail, the combined file size limit is 20 megabytes (MB) and for Exchange accounts (business email), the default combined file size limit is 10 MB.

Save your file to a cloud service and share a link

There are many cloud storage services to which you can upload and then share large files. Some popular cloud storage services include OneDrive, Dropbox, iCloud, and Google Drive. Once your file is stored in the cloud, you can include a link to the document in your email message.

  1. Upload your file to a cloud service, such as OneDrive or Dropbox.Note: The service you use generates a link to access your file. Your recipient can open the link to download your file.
  2. After you upload the file, copy the link, and paste it into your email message.Tip: For detailed information about uploading files and creating a download link in OneDrive, go to Upload photos and files and Share files and folders and change permissions.

Compress the file

When you compress, or zip, your file, it decreases its size, and it might decrease it enough to fit within the Outlook size limits for attachments. The following articles describe how to compress and extract files for different Windows operating systems.

Reduce the size of an image

If you’re sending large image files you can automatically resize them to reduce their file size.
  1. Attach the images to your email message.
  2. Click File > Info.
  3. Under the Image Attachments section, select Resize large images when I send this message.User uploaded file
  4. Return to your message, and click Send.

Save the file to a SharePoint server library

If you’re using Outlook in a business environment and use SharePoint, you can save a file to a SharePoint library and share a link to the file. See Share a document using SharePoint or OneDrive for instructions.

Thank you for that information. Since you had not included any of this at the beginning, people have to start at the beginning for troubleshooting. Given that all is hosted inside and others are not experiencing the issue, I suggest you check your Outlook settings to see if you have something different than others in the office. If you are unable to locate something there, you may wish to head over to Microsoft and their Office for Mac forums for assistance, unless your IT department is aware of all the settings you should have on the computer and Outlook to handle your mail.
