GetMessageFast starts to receive errors from EXCHANGE when Ruler is downloading more than 21 messages

[petermolnar11]

Hello, dear staaldraad! Thank you for very useful tool!
I use this tool for downloading messages from EXCHANGE (body, attachments, receiver, sender). I am connecting to EXCHANGE via MAPI/HTTP. I am downloading messages from INBOX.

I am using GetMessageFast function with tags:

pidtagdisplayto = PropertyTag{PtypString8, 0x0e04}
pidtagsendername = PropertyTag{PtypString8, 0x0c1a}
pidtagbody = PropertyTag{PtypString8, 0x1000}

When ruler downloads more than 21 messages, GetMessageFast starts to receive errors(0x4de - CODE_NOT_FOUND) and I cant get body, sender and receiver for all next messages. Very strange behavior ...
I hope you can help me :-)

I tried this on another EXCHANGE server and result is 16 messages. Then I started to receive errors 0x4de from EXCHANGE (on GetMessageFast calls)

hey @petermolnar11

this is probably way too late, but have you looked at how I did this in Liniaal, where I never ran into this issue: https://github.com/sensepost/liniaal/blob/master/liniaal.go#L129-L167

hope that helps?
