Hello Team,

I have fetch out some stale active devices in exchange 2013 that not used from last 45 days. So found some 1000 devices status for Device access state is showing Blocked ..

So my question is, is it safe to remove those devices from exchange and also some of those devices below status is showing blank

LastPolicyUpdateTime       LastSyncAttemptTime       LastSuccessSync


Please suggest. in terms of removal will effect anything on exchange 2013

Thanks,
Andy

I guess you have created a ActiveSync policy to quarantine newly added devices and allow them manually or using policy. Blocked means the access to device is blocked either manually or using policy. I don't see any issue in removing the blocked devices as you are no allowing them to sync anyway. LastPolicyUpdateTime,LastSyncAttemptTime, LastSuccessSync showing blank because the device is not allowed to sync.

ok so that means that are safe to remove .

ok one more thing, which active sync devices we need to put in exception, like any system mailbox or any other mailbox type ?

I don't think any system mailbox will have ActiveSync device connected to it. You don't have to exclude any blocked devices unless you don't have a process in place to release the quarantined devices.

The problems with reply email signatures

Do you wish that you could place an email signature under a reply? Well, unfortunately, you can't. That great Exchange/Office 365 signature you've created will just appear at the bottom of an email chain. What a pain! Is there really no way to solve this? Well, there might be...

What I mean to say is, If you are allowing all ActiveSync devices without validating them using a quarantine or ActiveSync Policy. Then you should not remove the blocked devices as you don't want those devices automatically allowed when they try to reconnect to your environment. If you have a process to validate and allow the devices then you can remove, because if they try to reconnect then you can always block them. Hope it's clear!

Hello Subsun,

Thanks for this.
So there is no use to remove the blocked devices??? or they are using any resources of exchange.

i was thinking to make the database clean and tidy.. so thinking to remove all those Blocked devices too

Thanks,
Andy

There is no such performance impact, It more of a House keeping task to remove the stale devices to keep the exchange environment clean.
