HI,

When i attach picture through insert option in outlook in new email message, size not changing for the picture. But in same case if u insert picture in meeting request, that picture size getting increased. Like my picture size is 390KB. Receiving message size is 3MB. 

How to stop increasing the size...

Is there any particular reason for that..

Hi,

Any one help me on this issue...

Atleast i want to know the reason why the picture size changing after inserting into meeting request, where as it is not changing when inserting into new message...

Hi,

Sorry for the delay.

This is the default behavior of both Outlook and the Microsoft Rich Text Format (RTF) standard.

By default, Outlook set the meeting requests format to RTF, aiming at better transfer across the Internet to other Outlook users.

Rich Text Format (RTF) is a Microsoft Standard file format used in Office, WordPad, and other applications. RTF file is ASCII, and its image storage is extremely large in that each pixel gets encoded as a sequence of ASCII characters. For example by adding a 100kb JPEG image to an RTF document it can increase the file size by 5 MB.

Hope this helps.

Hi,

Is there any other way to compress images in meeting request..

Since that user will send lot of meeting request daily basis, that too he is having message sending size limit 2MB. Management not allowing to increase sending size...

We can use Attach File to include an image instead of clicking Pictures button to insert an image.

Hey Vino,

In Outlook 2010 you can also insert a text box and then insert the image inside the text box.  This doesn't stop the meeting size increasing, but it does significantly reduce the amount it increases by.

It looks like they've finally fixed it in Outlook 2016 Tech Preview.

Outlook	Original Image Size	Inserted Size	TextBox Size
2010	92KB	640KB	196KB
2013	92KB	481KB	272KB
2016TP	92KB	130KB	229KB

Hope that helps people in some way.

Thanks
Craig
