Native Mode

[quattro5vt]

We recently upgraded from Exchange 5.5 to 2000. This is our only Exchange server in the domain, so we want to run in native mode. The only problem is that the Change Mode button is greyed out and won't allow us to click it. Any thoughts would be appreciated. Thanks.

Sounds like replication services not being removed.

Thanks, that made the button available. Before I click on change mode, are there any side effects that I should worry about, such as a forced reboot, or something that might stop working if I change? Thanks.

Ashley,

Technet Article Q272314 (Preparing a Mixed Mode Org'n for Conversion to Native Mode) describes the steps to switch from Mixed to Native.

Good Luck,
Dave

Is anyone aware of any negetive issues with converting to Native mode? We are ready to convert, but I have a fear that something will stop working. We only have one server that we upgraded from 5.5 to 2000. Any suggestions would be greatly appreciated. Thanks.

I wouldn't call them negative issues, but here's the basic differences:
1) Mixed Mode can support downlevel exchange servers, Native can't
2) Mixed mode can handle only one routing group per administrative group, Native can handle multiple
3) Mixed mode can't move mailboxes between servers in separate administrative groups, Native can.
4) In Native mode, SMTP is the protocol of choice for all mail activity.
