Hi 

We had some application issues with exchange server 2010 with SP1, it has a mailbox role installed.due to this issue we formatted C drive alone and re-installed windows 2008 R2 (SP1) + exchange 2010 (SP1).

Server detecting OS updates but not exchange updates. i need to install updates rollup for exchange server.

Please guide me 

 Thanks

Hi,
Exchange 2010 SP1 is not supported anymore and could very well be the reason why no Rollups is detected.
You should be on at least SP2 or preferably SP3. Service packs must be downloaded and installed manually.

Microsoft Exchange Server 2010 Service Pack 3 (SP3)

Note: Your CAS and HUB Server should be patched before the Mailbox Role.

Hi, Thank you for the reply.Can I directly apply SP3 on SP1?
