How to decode Conversationid?

Kirill Kodryanu 0

Dear colleagues,

Could you please send a link to a working recipe on how to decode 'conversationid' string?
I use Graph API to get information about emails and I would like to know the order of the current email in the thread.
I'm trying to find this information but the only information I have found is the next link, which does not help very much: https://learn.microsoft.com/en-us/openspecs/exchange_server_protocols/ms-oxomsg/9e994fbb-b839-495f-84e3-2c8c02c7dd9b?redirectedfrom=MSDN
For example I have next value 'AAQkADQ0NDQ3MjIxLTgzYjAtNDQ2Yy04ODJlLTEyODVhMjdlMDkxNQAQALHBLAYaU2RIuhAuQp9mJeg='.
What is behind this string, hoe to decode it? Base64 doesn't work.
Thank you in advance for your support!

Hello Kirill Kodryanu,
Thank you for your post in this Q&A forum,

Unfortunately, there is no know way to decode the conversation id of an email message. On top of that ConversationId element contains the identifier of an item or conversation only. However, you can order current message by receive time/date, if there a Chan of emails.
Hope that helps.

Thank you very much for your reply.

I made a mistake, of course, I meant conversationIndex.

The link which I have posted follows the conversationIndex description web page.

What about this parameter? Is it possible to decode it and use it for ordering emails in a thread?

If no, what is the purpose of conversationIndex parameter?

Thank you in advance!

Hi Kirill Kodryanu,
Thank you for your response.
The conversationIndex holds a distinct value utilized to track an email's position within a conversation.
Unfortunately, there is not official article mentioned that we can decode this property value.
Let me know if you have any more questions.

Hi Kirill Kodryanu,
Thank you for your reply.

Unfortunately, this does not seem possible to decode conversationIndex. You can order current message by receive time/date, if there a Chan of emails. Not sure if that helps to achieve your goal.
Thanks

Hi @ab-8756,

Thank you very much for your prompt reply.
By the way, if I learn the official documentation I can find some information about conversationIndex: https://learn.microsoft.com/en-us/graph/api/resources/message?view=graph-rest-1.0#properties

Does this mean that, the information I have found in the official documentation isn't correct?
Unfortunately date and time are not a reliable source for organizing letters in order.
