Have an issue, where I ran out of drive space on the Exchange 2013 Data drive while migrating users. I added the space and everything seems fine. but now when I try to move users, it says it is syncing, yet nothing seems to happen. The event log shows the following.
The Microsoft Exchange Mailbox Replication service was unable to process a request due to an unexpected error.
Request GUID: '70194e76-d890-4392-b0fa-019fb27f71b5'
Database GUID: '52918bba-59ec-42bf-8ceb-90f33a7ed79d'
Error: Resource reservation failed for 'MdbWrite(Mailbox Database 0921641520)' (MdbLatency(Mailbox Database 0921641520)): load ratio 1.79769313486232E+308, load state 'Critical', metric 5787..
Any idea's what the issue is. The users that failed to move are fine on the exchange 2007 and the users that did move are fine on the Exchange 2013 server.
