PC DB: What the TID.GLB File Is Used For

The information in this article applies to:

Microsoft Mail for PC Networks, versions 2.1e, 3.0, and 3.2

The Microsoft Mail system maintains unique tuple identifiers (tids) in several file record structures. These tuple identifiers are used to guarantee the authenticity of each user's name.

For example, if John Smith has the mailbox name JohnS and eventually gets replaced with a new user named JohnS, the tuple identifier gets changed with the deletion and re-creation of the mailbox name. Any users who had the old JohnS in their Personal Address List would no longer have a valid address definition because the tuple identifiers (or "tids") would not match.
