Technical Exchange bLog

 If you are using Microsoft's Azure Backup server to backup your Exchange you might want to use notifications if anything goes wrong with it. In the Options window when you enter credentials for the sending account it keeps failing to send test E-mail saying wrong username and password (error 2013).  The problem is that this account needs to have local admin rights on the Azure backup machine.  Yeah, don't ask why.

We had a problem where M365 users could not retreive Free/Busy information from on-premise Exchange server. Hybrid setup was run and everything was working fine except this. After research I found out that TargetSharingEpr is the way to look at. There are many sites out there that are pointing to the same setting but only Set-OrganizationRelationship is used to change the value. The problem is, this value is available for two commands: Set-IntraOrganizationConnector Set-OrganizationRelationship While we changed the value in  Set-OrganizationRelationship it didn't work until we changed the value in  Set-IntraOrganizationConnector too. By default it should work with just  TargetAutodiscoverEpr but for us it didn't. Finally we ran this command on Intra Organization Connector which is used from Cloud to On-prem:  Set-IntraOrganizationConnector -TargetSharingEpr   https://mail.domain.com/ews/exchange.asmx And it worked.
