Hi, 

I have very strange error on my Exchange Org - we created some users and create mailboxes for them but randomly when some users log in to their mailboxes (using OWA or Outlook) they are not able to do.

They got an error from OWA telling Something wrong :(

There no common factor between them (different OUs, different Mailboxes DBs, different date of creation)

i tried the common troubleshooting steps

also i created new DBs also i got the same issue

Can any one help me     

Hi,

What is your detailed exchange environment?

Please add the error message you received in details .

On outlook side, please try to recreate a new profile to test.

On server side, please move the problematic mailbox to another mailbox datebase to test.

Regards,

David

I found the solution, after deep troubleshooting I found that all effected users has Last Login Value on ADSEDIT

but the are not able to access their Mail it's because Mailbox DB itself as it was damaged for this user tenants so when I disabled and enabled those users back they got a new mailboxes and working fine but I repaired the old DB and move the data for those users

Thanks
