Attachments and file storage in Dynamics 365.

Posted on by 10

Hi,

I've researched and am still not 100% sure where attachments and files are stored in Dynamics 365 Online. 

Is this correct?

Attachments in Dynamics 365 are stored in three different database tables:

Attachment (Email Attachment),

ActivityMimeAttachment (Email Attachment Metadata(uses ID ), 

Annotation (Note)

Is there also any difference to CRM 2011, is the data stored in the same way there?

Thanks for any help.

    Hi, but if for example I'm using Power Automate to connect to the different entities for Notes and Attachments, where do I find them?

    Is it correct to assume the following?

    Attachment Entity -> Email Attachment

    ActivityMimeAttachment -> Email Attachment Metadata(uses ID

    Annotation -> Note

    Thanks.

    Hi Johnny,

    In Dynamics 365 Online new storage model, there are 3 sections: Database, File and Logs. Attachments (regarding emails) and Notes (with attachment files) are under File section.

    Take note that Annotation table is under Database and File section. This means that there are some notes that don't have files attached.

    Please, access the address for more details: docs.microsoft.com/.../capacity-storage

    Comparing to Dynamics CRM 2011, the tables are the same, the only change is the way that information are allocated into online storage.

    You can have a better visibility here: docs.microsoft.com/.../whats-new-storage

    PS: Some Online customer are still under old storage model, where there no division and organization´s storage retains all tables under a unique section (Database).

    Thanks,
