We were attempting to do a mailbox restore with Veeam Backup & replication, and at one point it asked to link the ese.dll file in the bin folder. It did not specify in Veeams documentation exactly where this file is located so we linked it to the one we found on the live server. Now outlook cannot connect to exchange and we have 2 services that are failing to start: Microsoft Exchange Transport, and Microsoft Exchange RPC Client Access. they give an error of failed to start Error 5: Access is denied.
Not sure of where to go from here. can we run something from the eseutil.exe to fix this or what are our options.
Any help would be great!
