Hi,

I have put MaximumAttachmentSize=0 in the registry to bypass the first limitation of size.but if I try to attach a file of 2,2 Go i have again the message that it is bigger that the maximum size allowed by the server.

So I have tryed to put values in the property of store PR_MAX_SUBMIT_MESSAGE_SIZE and PR_PROHIBIT_SEND_QUOTA but I get always the warning message ....I use outlook 2013

no we have a googlemail enterprise account in our company.I have looked at the preferences of my gmail account but I haven't found something to modify the size.I can attach a 1,7 Go file but not a 2,2 Go file. (with the 32 bits version of Outlook because I will try with the 64 bits version too, because  I must do a 64 bits version too of my addin)

Hi,

I have putted MaximumAttachmentSize=0 (size unlimited) but If I try to add an attachment of 2,2Go with the outlook button, it doesn't add it in the mail(it is ok for 1,7Go).

I am making an outlook Addin with ATL COM C++. A big part ot the addin is done now.

I have added a new button to attach file but the function Attachment::add fails with E_FAIL when adding a 2,2 Go file.it is the only way to add an attachment...I don't know how to bypass this limitation.  I will try  sizes between 1,7 Go and 2,2 to find exactly the limitation size. I can perhaps too try to put a MaximumAttachmentSize bigger.

We can attach a file up to 1,96 Gb in Outlook (64 bits).(2 056 410 Kb)

Hi stephane_l2,

As I don't have the same scenario and add-in here, I think we can try this. Instead of setting it as 0, make it larger than 1.96 GB and check the result again.

Important Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.

Hi,

I have put 10 Gb (in Kb) in MaximumAttachmentSize.it doesn't change anything and I cannot attach a file bigger than 1,96 Gb.
