Identifier: | 0x0E18 |
Property type: | PT_LONG |
Property tag: | 0x0E180003 |
The PR_MESSAGE_DOWNLOAD_TIME property is expressed in seconds and represents the best estimate of the time it would take a remote transport provider to download a given message from its current location to a message store local to the client viewing the header folder. The remote transport provider typically calculates PR_MESSAGE_DOWNLOAD_TIME by dividing the value of the PR_MESSAGE_SIZE property by the speed of the communications link in bytes per second. If the provider cannot calculate the download time, for example if it does not know the link speed, it should furnish a PT_ERROR value such as MAPI_E_NO_SUPPORT for this column in the header folder contents table.
