Released: July 2021 Exchange Server Security Updates

Problems with Schema update VERSION rangeUpper; Exchange 2013

The understanding is that the rangeUpper value for the ms-Exch-Schema-Version-Pt attribute should increment from 15312 to 15313.

I've installed the security update on my Exchange-server and run the schema update but the rangeUpper value is staying at 15312.

The release notes file versions entries say that the Schemaversion.ldf file should be dated 7/7/21, size 1,905 bytes.

On all servers I have run the security update but the Schemaversion.ldf file is staying at 05/29/19.

The following LDF's ARE getting updated although they are dated 07/08/21 rather than the 07/07/21 listed in the notes,

Anyone else have the same problem?

I think that when the rangeUpper is still the old version Exchange is still vulnerable.......or am i wrong?
