Dell Migration Manager 8.14 for exchange - Outlook slow

Ajit
over 6 years ago

Issue noticed : Users complain that outlook is sluggish / status shows disconnected at random intervals

On investigation it was found that the users were part of migration batch and the migration copy process is causing this issue

Users are using outlook in online mode (VDI ) and also users are using cached exchange mode in laptops.

On exchange servers we notice lsass process is using high cpu.

Could you please advise any hotfix which can resolve this issue or is this a known issue.

Then we can schedule migration only during off business hours.

Exchange server OS : Windows 2012 R2

Exchange version : 2013 CU15

Outlook 2010 SP2

Thank you

Ajit

    My apologies, I did missunderstand that the users are "Currently" in a migration batch.

    I can understand that if the mail agents are running, that your environment will see some impact, there isn't much we can do about that. The Disks/Attached storage will see lots of usage, along with other resources in your exchange environment. This is somewhat expected during processing.

    You may wish to not process so many mailboxes at once if the environment cannot handle the impact. Perhaps disable a collection, and see if this helps.

    Per below though, if you are using RUCs, then the users cannot be logged into their mailboxes. It will absolutely cut them off/block access.
